1 About Zero Downtime Migration

Zero Downtime Migration gives you a way to simplify moving your on-premise databases and Oracle Cloud Infrastructure Classic instances to Oracle Cloud Infrastructure, Exadata Cloud at Customer, and Exadata Cloud Service, without incurring any significant downtime, by leveraging technologies such as Oracle Active Data Guard.

Zero Downtime Migration uses mechanisms such as backing up the source database to Oracle Cloud Infrastructure Object Storage, creating a standby database (with Oracle Data Guard Maximum Performance protection mode and asynchronous (ASYNC) redo transport mode) in the target environment from the backup, synchronizing the source and target databases, and switching over to the target database as the primary database.
