I would of thought going to 126.96.36.199 as an intermediate step is the way to go.
Is there a complication stopping you doing this?
Well I'd like to avoid any unnecessary steps. Doing two database upgrades instead of one in a downtime window is kind of a big deal.
I'm also throwing in ASM, AD/TXK upgrades, FMW upgrades, latest PSUs, ETCC patches, etc.
This is essentially just due diligence for the pre-upgrade process. If we have to have 188.8.131.52 as an intermediate step, then that really should be clearly defined in the documentation, should it not? Right now it's just a logical assumption.
You can review below MOS Notes for DB Upgrade Path:
Oracle Database Upgrade Path Reference List (Doc ID 730365.1)
I would be able to assist you if I know your exact requirement.
Are you doing an upgrade from 12.0 or 12.1 to 12.2. If yes, what are your EBS App & DB Versions.
You can upgrade from 184.108.40.206 to 220.127.116.11. There is no need to go for intermediate upgrade to 18.104.22.168 first.
