i upgrade my DB to 184.108.40.206 .
now i need to upgrade Apps to R12.1.1 is it true ? and can i finish my upgrade process ?
or start my Upgrade process from scratch and upgrade DB from 220.127.116.11 to 10.2.0.4 and then upgarde apps to R12.1.1 then upgrade DB to 18.104.22.168You do not need to go back to 22.214.171.124, and it is always recommended you be on the latest database version before upgrading to R12.
