How to revert the CM for z/OS server to the previous version after the upgrade

Question & Answer


Question

After running the ICMMLSUP and ICMMRMUP jobs to upgrade the CM z/OS environment on z/OS, what are steps needed to revert the CM z/OS environment to the previous version?

Cause

The testing of the upgraded environment failed.

Answer

The CM z/OS upgrade jobs changed the CM database content. Prior to V8.4.3, customers had to make a back up copy of the CM database before doing upgrades.

CM V8.4.3 for z/OS supports the ability to revert to a previous version of CM without using the back up copy.

See the attached document for the steps to use this function.
