Expanding Azure Arc SQL Migration with a New Target: SQL Server on Azure Virtual Machines
Modernizing a SQL Server estate is rarely a single-step effort. It typically involves multiple phases, from discovery and assessment to migration and optimization, often spanning on-premises, hybrid, and cloud environments. SQL Server enabled by Azure Arc simplifies this process by bringing all migration steps into a single, cohesive experience in the Azure portal. With the March 2026 release, this integrated experience is extended by adding SQL Server on Azure Virtual Machines as a new migration target in Azure Arc. Arc-enabled SQL Server instances can now be migrated not only to Azure SQL Managed Instance, but also to SQL Server running on Azure infrastructure, using the same unified workflow. Expanding Choice Without Adding Complexity By introducing SQL Server on Azure Virtual Machines as a migration target, Azure Arc now supports a broader range of migration strategies while preserving a single operational model. It becomes possible to choose between Azure SQL Managed Instance and SQL Server on Azure VMs without fragmenting migration tooling or processes. The result is a flexible, scalable, and consistent migration experience that supports hybrid environments, reduces operational overhead, and enables modernization at a controlled and predictable pace. One Integrated Migration Journey A core value of SQL Server migration in Azure Arc is that the entire migration lifecycle is managed from one place. Once a SQL Server instance is enabled by Azure Arc, readiness can be assessed, a migration target selected, a migration method chosen, progress monitored, and cutover completed directly in the Azure portal. This approach removes the need for disconnected tools or custom orchestration. The only prerequisite remains unchanged: the source SQL Server needs to be enabled by Azure Arc. From there, migration is fully integrated into the Azure Arc SQL experience. A Consistent Experience Across Migration Targets The migration experience for SQL Server on Azure Virtual Machines follows the same model already available for Azure SQL Managed Instance migrations in Azure Arc. The same guided workflow, migration dashboard, and monitoring capabilities are used regardless of the selected target. This consistency is intentional. It allows teams to choose the destination that best fits their technical, operational, or regulatory requirements without having to learn a new migration process. Whether migrating to a fully managed PaaS service or to SQL Server on Azure infrastructure, the experience remains predictable and familiar. Backup Log Shipping Migration to SQL Server in Azure VM Migration to SQL Server on Azure Virtual Machines is based on backup and restore, specifically using log shipping mechanism. This is a well-established approach for online migrations that minimizes downtime while maintaining control over the cutover window. In this model, database backups need to be uploaded from the source SQL Server to Azure Blob Storage. The migration engine will restore the initial full backup followed by ongoing transaction log and diff. backups. Azure Blob Storage acts as the intermediary staging location between the source and the target. The Azure Blob Storage account and the target SQL Server running on an Azure Virtual Machine must be co-located in the same Azure region. This regional alignment is required to ensure efficient data transfer, reliable restore operations, and predictable migration performance. Within the Azure Arc migration experience, a simple and guided UX is used to select the Azure Blob Storage container that holds the backup files. Both the selected storage account and the Azure VM hosting SQL Server must reside in the same Azure region. Once the migration job is started, Azure Arc automatically restores the backup files to SQL Server on the Azure VM. As new log backups are uploaded to Blob Storage, they are continuously detected and applied to the target database, keeping it closely synchronized with the source. Controlled Cutover on Your Terms This automated restore process continues until the final cutover is initiated. When the cutover command is issued, Azure Arc applies the final backup to the target SQL Server on the Azure Virtual Machine and completes the migration. The target database is then brought online, and applications can be redirected to the new environment. This controlled cutover model allows downtime to be planned precisely, rather than being dictated by long-running restore operations. Getting started To get started, Arc enable you SQL Server. Then, in the Azure portal, navigate to your Arc enabled SQL Server and select Database migration under the Migration menu on the left.

The new migration capability in the Azure SQL Migration extension provides an end-to-end experience to modernize SQL Server to Azure SQL Database. The extension allows you to perform a migration readiness check with actions to remediate possible migration blockers, export the assessment results, and get right-sized Azure recommendations.
