About Migrating Databases
You can migrate an entire active container database (CDB) or non-CDB database to
an Oracle Database Appliance machine by using the RMAN duplicate command.
When using RMAN Duplicate, ensure to have network connectivity from source and
target databases:
• Source database: The existing database to be migrated.
• Target database: The new database created on an Oracle Database Appliance
environment.
If you do not have network connectivity between the source and the target
environments, you can use the offline migration method. Offline migration uses RMAN
backup sets for duplication, which does not require connectivity to the primary
database.
At a high level, the procedure involves the following steps:
Deploy or update Oracle Database Appliance to the latest version.
1.
Confirm that the provisioning completed successfully.

•
Create an instance only database from the command-line interface.

If you have a bare metal platform, use the command odacli list-jobs
and the command odacli describe-job to verify the status.
If you have a virtualized platform, use the command oakcli list-jobs and
the command oakcli describe-job to verify the status.
If you have a bare metal platform, use the command odacli create-
database with the instanceonly flag on an Oracle Database Appliance
machine. The new database is the target database.
If you have a virtualized platform, use the command oakcli create-
database with the instanceonly flag on an Oracle Database Appliance
machine. The new database is the target database.
