Your company wants to migrate its MySQL, PostgreSQL, and Microsoft SQL Server on-premises databases to Google Cloud. You need a solution that provides near-zero downtime, requires no application…

Native export and import requires the source database to be offline or frozen during the export, resulting in significant downtime and no continuous synchronization.

Database links are an Oracle-specific concept and are not a standard Google Cloud migration mechanism for MySQL, PostgreSQL, or SQL Server.

Dataflow is a general-purpose data processing service and is not specifically designed for database migration with built-in CDC and schema replication support.

Database Migration Service natively supports MySQL, PostgreSQL, and SQL Server as source databases and uses change data capture (CDC) to continuously replicate ongoing changes from the source to the destination. This enables near-zero downtime migrations because the destination stays synchronized with the source until the final cutover, requiring no application-level changes.
