Announcing retirement of Microsoft Data Migration Assistant (DMA) Tool
Announcement As part of our ongoing commitment to deliver streamlined and modern migration solutions, Microsoft regularly evaluates its tools and services to ensure they meet evolving customer needs. In line with this effort, we are announcing the retirement of the Microsoft Data Migration Assistant (DMA) tool, effective July 16, 2025. After this date, the DMA tool will no longer be available for download from the Microsoft Download Center. Important Dates Announcement date: June 16, 2025 Retirement date: July 16, 2025 Alternative Options for Migration and Assessment As DMA reaches the end of its lifecycle, customers are encouraged to leverage alternative tools and features for assessment and data migration. Below, we outline the alternatives: Upgrade to higher version of SQL Server If you are seeking to upgrade to higher versions of SQL Server you can now use the new Migration component integrated into SQL Server Management Studio (SSMS). For detailed steps please see documentation for version upgrade using SSMS here: https://learn.microsoft.com/ssms/migrate-sql-server-component Migration to Azure SQL If you relied on DMA for assessments and migration to Azure SQL you have several options: SQL Server enabled by Azure Arc (Assessments) In addition to all the core benefits of enabling Azure Arc, SQL Server enabled by Azure Arc also provides automatic migration assessments that are continuously updated on a weekly schedule by default. See more details of the continuous Migration Assessment in SQL Server enabled by Azure Arc here : https://learn.microsoft.com/sql/sql-server/azure-arc/migration-assessment Azure Database Migration Service (DMS) automation using Azure Powershell and Azure CLI You can use the datamigration module in Azure PowerShell and Azure CLI to perform assessments and migration. The ability to script and automate enables migration factory pattern approaches. See the documentation for automating assessments and migrations here : https://learn.microsoft.com/ azure/dms/migration-dms-powershell-cli. You can also find more information and sample scripts here: https://github.com/Azure-Samples/data-migration-sql Azure Portal Azure Migrate (Assessments) For large scale assessments such as datacenter exit scenarios, the Azure Migrate provides SQL Assessment at scale. Deploying the Azure Migrate appliance facilitates discovery, assessment, and business case evaluation at large scale for not just SQL Server but many other workloads as well. Learn more about SQL assessments in Azure Migrate here: https://learn.microsoft.com/en-us/azure/migrate/how-to-create-azure-sql-assessment Azure Database Migration Service (Migration) For SQL Server migration to Azure SQL offerings, you can use the Azure Database Migration Service (DMS). This service supports migration to all Azure SQL offerings. For example, see how you can migrate to Azure SQL DB using DMS portal here : https://learn.microsoft.com/data-migration/sql-server/database/database-migration-service?tabs=portal. Additional Information Azure Data Studio is on the deprecation path and we are building the replacement assessment and migration experiences in SQL Server Management Studio (SSMS) 1 . Till then, for smaller scale scenarios, you can continue to use the Azure SQL Migration extension in Azure Data Studio (ADS) for assessment and migration to Azure SQL.

This will ensure smooth continuity in your migration and assessment workflows. Thank you for your understanding and cooperation during this transition.
