Hi Expert,
Good evening/Good Morning.
I was requested to Upgrade the database which is running on 12.1.0.2 to 19.X which is running on RHEL ,but the question is what are the Things i need to consider Before and After DB upgrade from 12c to 19c where this db is source of gg uni-direction replication setup.
GG(19.1) perspective , what are the checks or config change i need to do in order to avoid post upgrade replication issue.
Thanks
Bala
