My question is which database oracle_home we have to consider to upgrade R12? and What about another one oracle_home?
When you run Rapid Install, provide the details of the already upgraded/installed 18.104.22.168 ORACLE_HOME.
For 11gR1 ORACLE_HOME which is installed by Rapid Install, please see (How to upgrade Oracle E-Business Suite from 11i to 12.1.1 and keep the existing 10g Database? (Doc ID 1345020.1)).
I can able to upgrade DB from 9i to 11gR2 directly, while upgrading 11i to R12, I confused a lot on following this document "Oracle E-Business Suite Upgrade Guide: Release 11i to Release 12.1.1, Part Number E14010-01". Kindly give me what are the specific steps to upgrade from 11i to R12.1.1?
Thanks & Regards
