help Oracle Zero Downtime Migration FAQ

What underlying technology powers Oracle Zero Downtime Migration?

Oracle Zero Downtime Migration (ZDM) is powered by CloudEndure Migration technology, which Oracle licenses to facilitate continuous data replication. This engine works at the block level to asynchronously replicate databases and applications to the cloud without interrupting active processes.

Can Oracle ZDM be used to migrate databases to cloud providers other than Oracle Cloud Infrastructure (OCI)?

No, Oracle Zero Downtime Migration is a purpose-built tool designed exclusively to move on-premises workloads into Oracle Cloud Infrastructure (OCI). It is optimized for moving Oracle databases to OCI services like Exadata Cloud Service or Base Database.

How does Oracle Zero Downtime Migration handle the cutover phase?

ZDM orchestrates the transition by keeping the target cloud database perfectly synchronized with the on-premises source up until the final cutover. Once you trigger the cutover, it stops the source database, applies the final delta of data, and brings the cloud instance online, minimizing application downtime.

Does Oracle ZDM support migrating Autonomous Databases?

Yes, Oracle Zero Downtime Migration includes dedicated workflows to seamlessly migrate on-premises Oracle databases to Autonomous Database targets within OCI. This handles the specific networking, data transfer, and configuration parameters required by Oracle's highly automated database platform.
