We’re excited to introduce the next improvement in Hyperscale conversion: a new preview feature that allows customers to convert Azure SQL databases to Hyperscale by keeping active geo-replication or failover group configurations intact. This builds on our earlier improvements and directly addresses one of the most requested capabilities from customers. With this improvement, customers can now modernize your database architecture with Hyperscale while maintaining business continuity. Overview We have heard feedback from customers about possible improvements we could make while converting their databases to Hyperscale. Customers complained about the complex steps they needed to perform to convert a database to Hyperscale when the database is geo-replicated by active geo-replication or failover groups. Previously, converting to Hyperscale required tearing down geo-replication links and recreating them after the conversion. Now, that’s no longer necessary. This improvement allows customers to preserve their cross-region disaster recovery or read scale-out configurations and still allows conversion to Hyperscale which helps in minimizing downtime and operational complexity. This feature is especially valuable for applications that rely on failover group endpoints for connectivity. Before this improvement, if application needs to be available during conversion, then connection string needed modifications as a part of conversion because the failover group and its endpoints had to be removed. With this new improvement, the conversion process is optimized for minimal disruption, with telemetry showing majority of cutover times under one minute. Even with a geo-replication configuration in place, you can still choose between automatic and manual cutover modes, offering flexibility in scheduling the transition. Progress tracking is now more granular, giving customers better visibility into each stage of the conversion, including the conversion of the geo-secondary to Hyperscale. Customer feedback Throughout the private preview phase, we have received overwhelmingly positive feedback from several customers about this improvement. Viktoriia Kuznetcova, Senior Automation Test Engineer from Nintex says: We needed a low-downtime way to move our databases from the Premium tier to Azure SQL Database Hyperscale, and this new feature delivered perfectly; allowing us to complete the migration in our test environments safely and smoothly, even while the service remained under continuous load, without any issues and without needing to break the failover group. We're looking forward to the public release so we can use it in production, where Hyperscale’s ability to scale storage both up and down will help us manage peak loads without overpaying for unused capacity. Get started The good news is that there are no changes needed to the conversion process. The workflow automatically detects that a geo-secondary is present and converts it to Hyperscale. There are no new parameters, and the method remains the same as the existing conversion process which works for non-geo-replicated databases. All you need is to make sure that: You have only one geo-secondary replica because Hyperscale doesn't support more than one geo-secondary replica. If a chained geo-replication configuration exists, it must be removed before starting the conversion to Hyperscale. Creating a geo-replica of a geo-replica (also known as "geo-replica chaining") isn't supported in Hyperscale. Once the above requirements are satisfied, you can use any of the following methods to initiate the conversion process. Conversion to Hyperscale must be initiated starting from the primary geo-replica. The following table provides sample commands to convert a database named WideWorldImporters on a logical server called contososerver to an 8-vcore Hyperscale database with manual cutover option. Method Command T-SQL ALTER DATABASE WideWorldImporters MODIFY (EDITION = 'Hyperscale', SERVICE_OBJECTIVE = 'HS_Gen5_8') WITH MANUAL_CUTOVER; PowerShell Set-AzSqlDatabase -ResourceGroupName "ResourceGroup01" -ServerName "contososerver" -DatabaseName "WideWorldImporters" -Edition "Hyperscale" -RequestedServiceObjectiveName "HS_Gen5_8" -ManualCutover Azure CLI az sql db update --resource-group ResourceGroup01 --server contososerver --name WideWorldImporters --edition Hyperscale --service-objective HS_Gen5_8 --manual-cutover Here are some notable details of this improvement: The geo-secondary database is automatically converted to Hyperscale with the same service level objective as the primary. All database configurations such as maintenance window, zone-resiliency, backup redundancy etc. remain the same as earlier (i.e., both geo-primary and geo-secondary would inherit from their own earlier configuration). A planned failover isn't possible while the conversion to Hyperscale is in progress. A forced failover is possible. However, depending on the state of the conversion when the forced failover occurs, the new geo-primary after failover might use either the Hyperscale service tier, or its original service tier. If the geo-secondary database is in an elastic pool before conversion, it is taken out of the pool and might need to be added back to a Hyperscale elastic pool separately after the conversion. The deployment of the feature is in progress and is expected to be completed in all Azure regions in a few weeks. In case you see error (Update to service objective '<SLO name>' with source DB geo-replicated is not supported for entity '<Database Name>') while converting primary to Hyperscale, wait for this new improvement to become available in your region. If you don’t want to use this preview capability yet, make sure to remove any geo-replication configuration before converting your databases to Hyperscale. Conclusion This update marks a significant step forward in the Hyperscale conversion process, offering simple steps, less downtime and keeping the geo-secondary available during the conversion process. We encourage you to try this new capability and provide your valuable feedback and help us refine this feature for general availability.

Simplified & lower pricing for Azure SQL Database and Azure SQL Managed Instance backup storage
Today as you deploy your Azure SQL database or Azure SQL managed instance, one of the important decisions to be made is the choice for your backup storage redundancy (BSR). I say it's important because the availability of your database depends on the availability of your backups. Here’s why. Consider the scenario where your DB has high availability configured via zone redundancy. And, let's say, your backups are configured non-zone redundant. In the event of a failure in the zone, your database fails over to another zone within the region, however your backups won't, because of their storage setting. Now, in the new zone, the backup service attempts to backup your database but cannot reach the backups in the zone where the failure happened causing the logs to become full and eventually impacting the availability of the database itself. As you create the Azure SQL database, the choices for backup storage redundancy are: Locally Redundant Storage (LRS) Zone Redundant Storage (ZRS) Geo Redundant Storage (GRS) and Geo Zone Redundant Storage (GZRS) Each of these storage types provides different levels of durability, resiliency and availability for your databases and database backups. Not surprisingly, each storage type also has different levels of pricing, and the price increases significantly as the protection level increases with GZRS storage type almost 4-5x LRS. Choosing between resilience and cost optimization is an extremely difficult choice that the DB owner must make. We are thrilled to announce that, starting from Nov 01, 2024, the backup storage pricing is now streamlined and simplified across Azure SQL database and Azure SQL Managed Instance. Bonus – we even reduced the prices 😊 The price changes apply to the Backup Storage Redundancy configuration for both Point-in-time and Long-Term Retention backups, across the following tiers of Azure SQL Database and Azure SQL Managed Instance: Product Service Tier Azure SQL Database General Purpose Business Critical Hyperscale Azure SQL Managed Instance General Purpose Business Critical Next Generation General Purpose (preview) As we made the changes, following were the principles we adhered to: No price increase BSR pricing for ZRS is reduced to match the BSR pricing for LRS BSR pricing for GZRS is reduced to match the BSR pricing of GRS BSR pricing for GRS/GZRS will be 2x that of LRS/ZRS Type of backups What is Changing PITR BSR pricing for ZRS is reduced by 20% to match pricing for LRS for all service tiers in Azure SQL Database and Azure SQL Managed Instance except for Azure SQL Database Hyperscale service tier. BSR pricing for GZRS is reduced by 41% to match pricing for GRS for all service tiers in Azure SQL Database and Azure SQL Managed Instance. LTR BSR pricing for ZRS is reduced by 20% to match pricing for LRS for all service tiers in Azure SQL Database and Azure SQL Managed Instance. BSR pricing for GZRS is reduced by 41% to match pricing for GRS for all service tiers in Azure SQL Database and Azure SQL Managed Instance. As an example, lets take East US as the region and look at the pricing for backup storage redundancy for Point in Time storage before and after the changes: For General Purpose/Business Critical service tiers the pricing would now be: Backup Storage Redundancy Current price New Price Price change LRS $0.10 $0.10 None ZRS $0.125 $0.10 20% less GRS $0.20 $0.20 None GZRS $0.34 $0.20 41% less For Hyperscale service tier, the new pricing would now be: Backup Storage Redundancy Current price New Price Price change LRS $0.08 $0.08 None ZRS $0.1 $0.10 None GRS $0.20 $0.20 None GZRS $0.34 $0.20 41% less Similarly, Backup storage redundancy prices for Long Term Retention backups in East US would be as follows: Backup Storage Redundancy Current price New Price Price change LRS $0.025 $0.025 None ZRS $0.0313 $0.025 20% less GRS $0.05 $0.05 None GZRS $0.0845 $0.05 41% less As a customer, the decision now becomes much easier for you. If you need regional resiliency: choose Zone Redundant Storage (ZRS) If you need regional and/or geo resiliency: choose Geo Zone Redundant Storage (GZRS). If the Azure region does not support Availability Zones, then choose Local Redundant Storage for regional resiliency, and Geo Redundant Storage for geo resiliency respectively. Please Note: The Azure pricing page and Azure pricing calculator will be updated with these new prices soon. The actual pricing meters have already been updated. Additionally, the LTR pricing change for Hyperscale will be in effect from January 1, 2025.Conversion to Hyperscale: Now generally available with enhanced efficiency
We are excited to announce the general availability (GA) of the latest improvements in the Azure SQL Database conversion process to Hyperscale. These improvements bring shorter downtime, better control, and more visibility to the Hyperscale conversion process, making it easier and more efficient for our customers to switch to Hyperscale. Key enhancements We received feedback from customers about longer-than-expected downtime, lack of visibility, and unpredictable cutover time during database conversion to Hyperscale. In response, we have made key improvements in this area. 1. Shorter cutover time Prior to this improvement, the cutover time depended on the database size and workload. With the improvement we have significantly reduced the average cutover time (effective unavailability of the database for the application) from about six minutes, sometime extending to thirty minutes, to less than one minute. 2. Higher log generation rate By improving synchronizing mechanisms between source and destination while the conversion is in progress, we now support a higher log generation rate on the source database, ensuring that the conversion can complete successfully with write intensive workloads. This enhancement ensures a smoother and faster migration experience, even for high-transaction rate environments. We now support up to 50 MiB/s log generation rate on the source database during conversion. Once converted to Hyperscale, the supported log generation rate is 100 MiB/s, with higher rate of 150 MiB/s in preview. 3. Manual cutover One of the most significant improvements is the introduction of a customer-controlled cutover mode called manual cutover. This allows customers to have more control over the conversion process, enabling them to schedule and manage the cutover at the time of their choice. You can perform cutover within 24 hours once conversion process reaches “Ready to cutover” state. 4. Enhanced progress reporting Improved progress reporting capabilities provide detailed insights into the conversion process. Customers can now monitor the migration status in real-time, with clear visibility into each step of the process. Progress reporting is available via T-SQL, REST API, PowerShell, Azure CLI, or in the Azure portal. Detailed progress information about conversion phases provides greater transparency and control over the process. How to use it? All the improvements are applied automatically. Once exception is the manual cutover mode, where you need to use a new optional parameter in T-SQL, PowerShell, Azure CLI, or REST API while initiating the conversion process. The Azure portal also provides a new option to select manual cutover as shown in below image. Granular progress reporting is available irrespective of the cutover mode. One of our customers said - The migration to Hyperscale using the improvements was much easier than expected. The customer-controlled cutover and detailed progress reporting made the process seamless and efficient. For more information, see our documentation: Convert a Database to Hyperscale - Azure SQL Database | Microsoft Learn Conclusion We are thrilled to bring these enhancements to our customers and look forward to seeing how they will transform their Hyperscale conversion experience. This update marks a significant step forward in the Hyperscale conversion process, offering faster cutover time, enhanced control with a manual cutover option, and improved progress visibility. You can contact us by commenting on this blog post and we’ll be happy to get back to you. Alternatively, you can also email us at sqlhsfeedback AT microsoft DOT com. We are eager to hear from you all!Improving the conversion to Hyperscale with greater efficiency
Update: On 09 April 2025 we announced the general availability this improvement. For more details, please read the GA announcement. We are thrilled to announce the latest improvement in the Azure SQL Database conversion process to Hyperscale. This update, now available in public preview, streamlines the database conversion process, reducing downtime and offering greater control and visibility to our customers. Let’s dive into the enhancements and what they mean for you. Overview We have heard feedback from customers about possible improvements we could make while converting their databases to Hyperscale. Customers complained about longer than expected downtime during conversion, no insights into the current state of conversion, and unpredictable cutover time. We acted on the feedback and made several key improvements in this release. 1. Shorter cutover time One of the most significant enhancements in this improvement is the reduction in cutover times when converting a database to Hyperscale. This improvement ensures that the cutover process is faster and more efficient, minimizing downtime and connectivity disruptions. Based on our telemetry, cutover time 99 th percentile has been reduced from ~6 minutes to less than ~1 minute. 2. Support for higher log generation rate During the migration, the new process supports a higher log generation rate on the source database, ensuring that the conversion can handle more write intensive workloads and complete successfully. In the previous version we saw that the database conversions were not able to finish when log generation on the source was more than 8 MiBps continuously, throughout the conversion process. With this improvement we can now support up to 50 MiBps log generation on source and still succeed. This was achieved by improving synchronizing mechanisms between source and destination while conversion is in progress. 3. Manual cutover A new option introduced with this improvement is manual cutover. This allows customers to initiate the conversion process and pause it when the database is ready to cutover to Hyperscale, giving them up to 72 hours to perform the cutover at a time that best suits their operational needs. If the manual cutover is not completed within the given timeframe, the process is automatically canceled, and the database remains on the original service tier, without any data loss. If the new parameter is not passed, then the cutover experience would be the same as earlier i.e. automatic cutover as soon as Hyperscale database is ready. 4. Granular progress reporting Another improvement in the conversion process is that now customers can monitor the entire conversion process at a granular level. Whether using T-SQL, REST API, PowerShell, Azure CLI or Azure portal, detailed progress information about conversion phases is available, providing greater transparency and control over the process. Customer feedback Throughout the private preview phase, we have received overwhelmingly positive feedback from several customers about this improvement. John Nafa, Cloud Architect, Asurgent says: The new database conversion experience from Microsoft has been incredibly seamless and efficient, making the conversion process to Azure SQL Database Hyperscale smooth and straightforward. The progress reporting and manual cutover features were especially valuable, providing real-time insights and ensuring a smooth transition. It’s been a pleasure working with this improvement, and I’m excited to see it become available to a wider audience. Get started Out of the four key improvements mentioned above, most are automatic. To utilize the manual cutover option, you need to use a new optional parameter in T-SQL, PowerShell, Azure CLI, or REST API while initiating the conversion process. Azure portal also provides a new option to select manual cutover. Granular progress reporting is available irrespective of the cutover mode. Use manual cutover Let us go through new options available in various interfaces with this improvement. Azure Portal To use manual cutover, a new Cutover mode option is provided in the Azure portal. The following screenshot shows the steps to convert a database to Hyperscale. The new option is shown under step 3. If you have not seen this option in the Azure portal yet, don’t worry. We are enabling this capability now and you can expect it to be available within days. Commands A new parameter has been introduced in each interface to initiate the conversion process with the manual cutover option. The following table provides sample commands to convert a database named WideWorldImporters on a logical server called contososerver to an 8-vcore serverless Hyperscale database. Method Command T-SQL ALTER DATABASE WideWorldImporters MODIFY (EDITION = 'Hyperscale', SERVICE_OBJECTIVE = 'HS_S_Gen5_8') WITH MANUAL_CUTOVER PowerShell Set-AzSqlDatabase -ResourceGroupName "ResourceGroup01" -ServerName "contososerver" -DatabaseName "WideWorldImporters" -Edition "Hyperscale" -requestedServiceObjectiveName "HS_S_Gen5_2" -ManualCutover Azure CLI az sql db update --resource-group ResourceGroup01 --server contososerver --name WideWorldImporters --edition Hyperscale --service-objective HS_S_Gen5_2 --manual-cutover Note: Additional parameters like backup storage redundancy or zone redundancy etc. can also be added. Refer documentation Set-AzSqlDatabase (Az.Sql) | Microsoft Learn (for PowerShell) and az sql db | Microsoft Learn (for Azure CLI). REST API also has new properties manualCutover and performCutover. Refer Databases - Create Or Update - REST API (Azure SQL Database) | Microsoft Learn for more details. Monitor the conversion progress The progress during this conversion can be monitored using various interfaces. Detailed phase information is available in the Dynamic Management View (DMV) sys.dm_operation_status for those using T-SQL. Similar command options are available for PowerShell and Azure CLI users. Azure Portal Progress of the conversion process can be seen by clicking on Details hyperlink as shown in the below screenshot at step 2. Monitoring programmatically As a part of this improvement, we have introduced new columns in the sys.dm_operation_status DMV called phase_code, phase_desc and phase_info which are populated during conversion process. Refer to documentation for more details. Similarly, new output columns, phase and phaseInformation, are available if using PowerShell under OperationPhaseDetails and if using Azure CLI under operationPhaseDetails. Here is the quick reference for commands via various interfaces. Method Command T-SQL SELECT state_desc, phase_code, phase_desc, JSON_VALUE(phase_info, '$.currentStep') AS currentStep, JSON_VALUE(phase_info, '$.totalSteps') AS totalSteps, phase_info, start_time, error_code, error_desc, last_modify_time FROM sys.dm_operation_status WHERE resource_type = 0 AND operation='ALTER DATABASE' AND major_resource_id = 'WideWorldImporters' PowerShell (Get-AzSqlDatabaseActivity -ResourceGroupName "ResourceGroup01" -ServerName "contososerver" -DatabaseName "WideWorldImporters").OperationPhaseDetails Azure CLI (az sql db op list --resource-group ResourceGroup01 --server contososerver --database WideWorldImporters | ConvertFrom-Json).operationPhaseDetails.phase Perform manual cutover The manual cutover, if specified, can be performed using the Azure portal or programmatically, ensuring a smooth transition to the Hyperscale tier. Azure Portal Cutover can be initiated from the same screen where progress of conversion is reported. Commands Here is the quick reference of the commands to perform cutover. Method Command T-SQL ALTER DATABASE WideWorldImporters PERFORM_CUTOVER PowerShell Set-AzSqlDatabase -ResourceGroupName "ResourceGroup01" -ServerName "contososerver" -DatabaseName "WideWorldImporters" -PerformCutover Azure CLI az sql db update --resource-group ResourceGroup01 --server contososerver --name WideWorldImporters --perform-cutover Conclusion This update marks a significant step forward in the Hyperscale conversion process, offering faster cutover time, enhanced control with a manual cutover option, and improved progress visibility.

Alternatively, you can also email us at sqlhsfeedback AT microsoft DOT com. We are eager to hear from you all! Frequently Asked Questions When does the change take effect, and what does it impact? The pricing changes take effect on December 15 th , 2023 at 00:00 hours UTC. The changes will apply to the following resources created on or after Dec 15 th , 2023. Any newly created Hyperscale single provisioned compute databases. Any (existing or new) Hyperscale single serverless databases (currently in preview). Any (existing or new) Hyperscale elastic pools (currently in preview). Any newly created Hyperscale elastic pooled databases (currently in preview). What happens to my existing Hyperscale resources? To start with, nothing changes till December 15 th , 2023. Here’s what will happen starting December 15 th , 2023: To provide a seamless experience without any impact on existing workloads, all existing Hyperscale single databases with provisioned compute created before December 15 th , 2023, will continue to be billed at the existing rates, for a period of up to 3 years (ending December 14 th , 2026). Customers will receive further notice of the pricing change to their Hyperscale databases in advance of December 14 th , 2026. All existing Hyperscale single databases with serverless compute (currently in preview) will automatically switch to the new pricing starting December 15 th , 2023. All existing Hyperscale elastic pools (currently in preview) will automatically switch to the new pricing starting December 15 th , 2023. What if I update / change a database to a different deployment option? Hyperscale allows seamless, rapid scaling of the database compute. You can also scale a Hyperscale database to move from provisioned compute to serverless compute (or the other way around). You can add an existing Hyperscale database to an elastic pool or move an elastic pooled database out of the elastic pool to a single database. Here’s how your costs are impacted if you perform any of these changes on or after December 15 th , 2023: Change Impact Hyperscale (serverless single, or elastic pooled) database is changed to a Hyperscale single database with provisioned compute. The final cost of the database will be based on when the database was created. If the database was created prior to December 15 th , 2023, it will be billed as per the existing pricing. If the database was created on or after December 15 th , 2023, it will be billed as per the new pricing. Hyperscale database is changed to a Hyperscale single database with serverless compute. The database will be billed with the new pricing. Hyperscale database is added to an elastic pool on or after December 15 th. The database’s storage will be charged as per the “new” storage pricing. There is no separate compute cost for a database in an elastic pool. Hyperscale single database with provisioned compute is scaled up, or down, or has high-availability replicas added or removed, or its hardware family is changed. The pricing model remains as it was before the scaling operation. The actual costs for compute resources will change based on the scaling operation (for example, they will increase if the database is scaled up, or replicas added). Do note that if you are using reserved capacity ("reservations") and are changing the hardware family, you will need to exchange those reservations to align to the new hardware family. The costs of storage resources associated with the single database will not change due to the scaling operation itself. Any copies of a Hyperscale database created as a Hyperscale single database, on or after December 15 th , 2023. The database copies will use the new pricing, regardless of when the original database was created. Any new single database created via. restore, or geo-replication operations, on or after December 15 th , 2023. The new database will use the new pricing, regardless of when the original database was created. Any non-Hyperscale database is updated to Hyperscale on or after December 15 th , 2023. The new database will use the new pricing, regardless of when it was originally created. See the summarized tables below for a quick reference.

With reservations, you make a commitment to use SQL Database for a period of one or three years to get a significant discount on the compute (vCores) costs. There are no changes to the Compute (vCores) pricing, and you can continue to use reserved capacity (“reservations”) for Hyperscale single databases with provisioned compute and Hyperscale elastic pools. How can I move my existing Hyperscale databases to the new pricing? Currently, there is no in-built support to switch pricing for existing Hyperscale databases. However, you can consider one of the redeployment methods (database copy, point-in-time restore, or geo-replication) to create a new “copy” of the existing Hyperscale database. The newly created “copy” of the database will be billed the new pricing. If you do decide to go down this path, do consider creating the new database with zone redundancy, as described here. Do you have any projections of likely costs when converting non-Hyperscale DBs to Hyperscale? We recommend you use the Azure pricing calculator to compare base cost for compute and storage. However, costs of backups can vary depending on the nature of the workload and backup retention settings configured. Databases in the (DTU) Basic, Standard and Premium service tiers include backup in the base cost. When converting such databases to Hyperscale, keep in mind that backups in Hyperscale can be a significant factor in overall cost. It is only possible to determine this after sufficient testing with realistic workloads on Hyperscale and we strongly recommend you do such testing before converting DTU service tier databases to Hyperscale. Does the reduction in compute price apply to all subscription offer types? In the case of dev/test subscriptions and related offer types including Enterprise dev/test, where you were already not paying for license costs, there will not be a further reduction in the price of compute. For such subscriptions, the storage costs for Hyperscale resources will still be based on the guidelines in the “When does the change take effect, and what does it impact?” and “What happens to my existing Hyperscale resources” sections in this blog post. Can I still use Azure Hybrid Benefit for Hyperscale? The change in price per vCore is done by eliminating the software license fee for Hyperscale resources. Hence, Azure Hybrid Benefit no longer applies to the Hyperscale tier, except for Hyperscale single databases with provisioned compute which were created prior to December 15, 2023. Even for those older databases, Azure Hybrid Benefit can only be used till December 14, 2026. Note that specifying values of BasePrice or LicenseIncluded for the LicenseType parameter in APIs / SDKs / PowerShell / CLI, is only relevant for Hyperscale single databases with provisioned compute which were created prior to December 15, 2023. These values are effectively ignored for all other types of Hyperscale resources. Current limitations and known issues Consider a database which was created originally as a non-Hyperscale database prior to Dec 15th, 2023. If this database is then migrated to Hyperscale on or after Dec 15th, 2023, the Cost Summary section of the Azure portal will incorrectly show the "old pricing" for this database. The Cost Summary section in the Azure portal is only intended to be an estimate. We recommend you rely on the Cost Management section in the Azure portal to review actual costs. Azure portal cost summary view in greater China regions does not show the updated pricing information accurately. This is only a display issue and does not impact the billing in any way. Please refer to the pricing calculator or the pricing page for accurate pricing information.
