Azure Database Migration Service (DMS) is Microsoft’s fully managed, cloud‑based service designed to simplify and accelerate the migration of databases to Azure with minimal downtime. It handles the movement of data, schema, and server‑level objects from SQL Server, MySQL, PostgreSQL, and MongoDB into Azure platforms like Azure SQL Database, Azure SQL Managed Instance, SQL Server on Azure VMs, and Azure Cosmos DB.
DMS integrates seamlessly with Azure Data Studio’s Azure SQL Migration extension, Azure Migrate, and PowerShell automations providing organizations with a guided, reliable, and scalable modernization pathway.
