How to Deinstall FMW Oracle Home Post Upgrade To 12.2.1.2 ?

(Doc ID 2256896.1)

Last updated on APRIL 21, 2017

Applies to:

Oracle Fusion Middleware - Version 12.2.1.2.0 and later
Information in this document applies to any platform.

Goal

Upgrade Oracle Fusion Middleware Infrastructure to the 12.2.1.2 

As the Upgrade Guide clearly states, "If you are upgrading from a previous 12c release (12.1.3.0, 12.2.1.0 or 12.2.1.1), then you must install the 12c (12.2.1.2) distributions into a new Oracle home. Do not attempt to reuse the existing Oracle home for this upgrade. Upgrading to 12c (12.2.1.2) is not a patch release."

Also from Oracle Fusion Middleware 12c Release 2 (12.2) Announcements (Doc ID 2067900.1)

“ This is a full installation with an out-of-place upgrade from previous releases. This does not update existing installations. “

So it is required to install the 12.2.1.2 in a new Oracle home.

However after completing the upgrade process successfully , is it required to maintain 2 Oracle Homes OR deinstall the older Oracle home (12.1.3.0, 12.2.1.0 or 12.2.1.1) and if so what is the procedure to do so?
