Database Migration Service documentation
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).
