You can use Database Migration Service to migrate your databases to Google Cloud. Database Migration Service supports both homogeneous migrations, such as MySQL to Cloud SQL for MySQL, and heterogeneous migrations, such as Oracle to Cloud SQL for PostgreSQL.
This page lists the versions of all source and destination databases that Database Migration Service supports in all migration scenarios. Use this information to choose the source and destination databases for your migration.
