Hi ,

I want to upgrade EBS R12.1.3 only DB version from to . Application version remain same. OS is RHEL 5 64 bit.

I review
Interoperability Notes EBS 12.0 and 12.1 with Database 11gR2 (Doc ID 1058763.1)

But some confusing about pre upgrade patches and post application upgrade, on application side
Can u suggest me steps contain all patches with upgrade steps properly.
If u got any clear procedure, it will be very nice

Thanks in advance.
