 Hello,

This is an Oracle recommended approach that I always follow: https://docs.oracle.com/en/database/oracle/oracle-database/19/upgrd/database-preparation-tasks-to-complete-before-upgrades.html#GUID-46F09541-C36A-4790-B3D3-E0E336A7BBC3

Before starting upgrades, update your new release Oracle Database to the latest Oracle bundle patch, patch set update (BP or PSU), or Release Update (Update), or Release Update Revision (Revision).

OJVM is required if that makes a difference 

It should be present in the 19c home then. There is the OJVM_STATUS pre-upgrade check that fails if OJVM is missing in the new home:Database Preupgrade tool check list. (Doc ID 2380601.1) Best regards,

Hello - quick advise question please!   What's the best approach when upgrading 12c to 19c?   Should I:
(1) apply the chosen RU to the 19c home before upgrading, or(2) should I upgrade first and then apply the RU?
This is a basic upgrade with the dbupgrade script (nothing fancy).  I presume both would work but I'm unsure what the best practice is (OJVM is required if that makes a difference). Thank you!Charlotte
