Unable to turn Secured Production Mode for a Production Mode Domain in 12.2.1.3 which was upgraded from 12.2.1

When we try to enable Secured Production Mode using the link reference https://docs.oracle.com/cd/E92951_01/wls/WLACH/taskhelp/domainconfig/ChangeToSecureMode.html we will see the below error in WebLogic Console.

An error occurred during activation of changes, please see the log for details.
