Azure Database Migration Services

Azure Database Migration Services, or DMS, is a fully managed Azure service that enables seamless migrations from multiple data sources to Azure databases.

Here are some examples of migrations that DMS can do:

• Migrate on-premises SQL Server to Azure SQL Database or SQL managed instance. Supports both online and offline migrations.
• Migrate Azure SQL Database to SQL database managed instances.
• Migrate an AWS SQL Server RDS instance to Azure SQL Database or SQL managed instance.
• Migrate MySQL to Azure Database for MySQL.
• Migrate PostgreSQL to Azure Database for PostgreSQL.
• Migrate MongoDB to Azure Cosmos DB Mongo API.

  Note

  Online migration is a migration with zero downtime or near-zero downtime during the cut-over to the migrated database.
