Execute a complete migration with near-zero downtime
Migrate your database and server objects—including user accounts, agent jobs, and SQL Server Integration Services (SSIS) packages—all at once.
Move widely used databases
Migrate your data to Azure from the most common database management systems. Whether you’re moving from an on-premises database or another cloud, Database Migration Service supports key migration scenarios such as SQL Server, MySQL, PostgreSQL, and MongoDB.
Automate your database migrations
Save time and effort by automating your move to Azure with PowerShell. Database Migration Service works with PowerShell cmdlets to automatically migrate a list of databases.
Simplify your migration with a two-step process
Better prepare your database workloads to move to Azure using the suite of Azure migration tools. First, use Azure Migrate to discover your on-premises data estate, assess migration readiness, and choose the best destination for your databases. Then, use Database Migration Service to move your on-premises databases to Azure.
Easily migrate to Azure SQL with Azure Data Studio
Migrate your SQL Server databases to Azure with the new Azure SQL Migration extension for Azure Data Studio. Using a familiar data migration software interface, expedite on-premises migrations to Azure SQL Virtual Machines and Azure SQL Managed Instance with low or zero application downtime.
Assess your SQL Server databases prior to migration
Before migrating your SQL Server databases to the cloud, use the Azure SQL Migration extension in Azure Data Studio to assess them and identify any issues that might arise during migration. The extension offers a user-friendly interface to run the assessment and generate right-sized configuration recommendations to meet your workload performance requirements.

Greg Matuskovic, Director, Global Solutions Architecture, Willis Towers Watson"The migration process would have taken us well over six months and days or weeks of downtime using any other method… Database Migration Service made our journey to the cloud practically seamless."
J.B. Hunt drives toward digital disruption
To cope with changes in the transportation industry and expand its capabilities, shipping and logistics provider J.B. Hunt launched a cloud-based digital service by migrating services to Azure Virtual Machines and the Web Apps feature of Azure App Service.
Jeff Schwartz, Hosted Services Manager, Innovative Systems"It took us under 16 hours to migrate the US database, almost 2 terabytes. Our preliminary tests showed it was going to take more like 24 hours, but working with the migration service team, we cut that by a third."
Christopher Keighley, Infrastructure Manager, Capita Reading Cloud"With Azure Database Migration Service, we only needed one person to migrate 10,000 databases. Any other way, we might have needed a team of 10 people to get it done."
