Moving to Oracle Cloud Using Zero Downtime
Migration 🔗
Oracle now offers the Zero Downtime Migration service, a quick and easy way to move
on-premises databases to Oracle Cloud Infrastructure.
Zero Downtime Migration leverages Oracle Active Data Guard to create a
standby instance of your database in an Oracle Cloud
Infrastructure system. You switch over only when you are ready,
and your source database remains available as a standby. Use the
Zero Downtime Migration service to migrate databases
individually or at the fleet level. See Move to Oracle
Cloud Using Zero Downtime Migration for more
information.
