Overview

Database Migration Service supports MySQL-to-Cloud SQL migrations where the destination is the same version or one version higher than the source database. For example, you can migrate a MySQL 5.6 source database to a Cloud SQL 5.6 or 5.7 destination, but you can't migrate from version 5.6 directly to 8.0.

See the following table for the full version compatibility matrix.
