which sequence the upgrade should be applied?
Hello,
We are currently running Oracle EBS r12.1.3 on Database 12c on Oracle Cloud Infra (OCI) and we need to upgrade to Oracle EBS r12.2.10 and database 19c on OCI.
What should be the correct order? Should we do DB upgrade first and then EBS Upgrade App tier or vice versa ?
Also what are steps of performing this upgrade specifically on OCI?
I have heard that we should do EBS upgrade first as 12.2.10 release comes with 19c database upgrade scripts that is uniquely applicable to upgrading the DB in EBS environments.
Is there any comprehensive MOS note or documentation reference available? If so, please share.
