Oracle 12c SE2 RAC support on Clusterware after upgrade to 19c
In order to test our application on 19c EE, I must upgrade a 12c Clusterware with some 12c SE2 RAC databases running on it to 19c.
What I want to end up with is a 19c Clusterware running on 2 nodes, all the old 12c SE2 RAC databases running on it, then create a new 19c EE RAC database on top of it.
I'm all set to start the rolling Clusterware upgrade to 19c, but will all the 12c SE2 RAC databases be compatible with 19c Clusterware after the upgrade?
I'm asking this because of "Desupport of Oracle Real Application Clusters (RAC) with Oracle Database Standard Edition 19c" 2504078.1.
Can you help me?
