126.96.36.199 is an un-existing release of Oracle WebCenter Portal as it were not releases in 12cR1, I will assume you talk about the first release of 12cR2 which is 12.2.1
In 12c the upgrade process has changed a bit compared to 11g releases and in "big words" means:
- Install separate Oracle Homes with the new release versions.
- Run some upgrade assistants
So move from 12.2.1 to 188.8.131.52 or the future release 184.108.40.206 (that will come soon) should not be a big challenge. (From 11g has little more challenges )
It is very well explained in the Oracle Documentation: https://docs.oracle.com/en/middleware/lifecycle/220.127.116.11/wccup/introduction-oracle-webcenter-12c-upgrade.html#GUID-2DCD1…
Thank you Daniel.
