Use DMS to shrink Cloud SQL for SQL Server disk
When database engineers hear “database migration", they typically think of a one-time onboarding pathway—moving databases from on-premises environments to the cloud, or between different cloud providers.
However, Google Cloud's Database Migration Service (DMS) supports Cloud SQL for SQL Server as a source. This opens up powerful, non-traditional operational patterns for SQL Server customers within Google Cloud.
