Upgrade rman catalog from 12.2 .0.1 to 19c
Hi ,
We have 12.2.0.1 databases backup by using rman catalog (12.2.0.1 also).
We have upgraded one database to 19c.
Unable to use rman to backup this 19c DB.
Should catalog be upgraded to 19c ?
If yes , what about Backup 12c DB ? Continue to work ?
Best regards.
