Cleanup 18c log files after autoupgrade of 18c non-CDB to 19c PDB

in Database Install/Upgrade/Opatch (MOSC) 2 commentsAnswered

Oracle database EE upgrade from 18c - 19c

I recently used the autoupgrade tool to upgrade an oracle restart single instance database from 18.14 to 19.19 and convert it to a PDB (non-CDB to PDB upgrade). We use ASM for our storage.

Post-upgrade, I still see flashback logs, controlfiles, archive logs, redo logs in ASM for the old 18c instance. I would like to get this cleaned up to free up the disk space. I can manually delete files in ASM but, in the past, deleting a large number of files this way has been known to cause problems. Anyone have any suggestions as to the best way to clean them up?
