Database Migration Service helps you migrate your data to Google Cloud. The service streamlines networking workflows, manages the initial snapshot and ongoing replication, and provides a status of the migration operations.

With Database Migration Service, you can perform minimal downtime migrations whether you keep the same database engine (homogeneous migrations) or switch to a different database engine (heterogeneous migrations). Go to the Database Migration Service product page for more.

Database Migration Service supports multiple different providers, SQL engines, and database versions. For the full list of supported databases, see Supported source and destination databases.
