Classification: Confidential Have no clue about AD/CD configuration. As I stated earlier, just point to new sysres and IPL. In my configuration PARMLIB/PROCLIB/IPLPARM *ARE NOT* on the sysres.

Maybe we're more constrained because it's an ADCD image? -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Pommier, Rex Sent: Tuesday, September 3, 2024 11:38 AM To: [email protected] Subject: Re: [EXTERNAL] Upgrading z/OS vs. z/VM Phil, I'm going to give you a qualified "nope" here. Granted I work at a small site - 2 production LPARs and a sandbox, no shared anything, no sysplex yadda yadda yadda. We currently have 3.1 sitting on a mod27 volume (with its unix filesystem datasets that shipped with it ready to go). Had to put new catalog entries into the master for the new USS datasets and new libraries on the RES pack - using indirect cataloging for it. IPLed 3.1 and ran for a few hours before we hit a snag that forced us to back out to 2.4. Backout was simply shutting down, pointing the hardware to the 2.4 SYSRES and IPLing. No messing with spool or anything else. Just need to make sure fallback maintenance is in place.

I will make assertions below, any/all of which may be wrong, but that seems better than qualifying each with "I think..." etc. Upgrading z/VM versions has been pretty trivial for quite a while: point to a new CP module, reIPL. Upgrading z/OS is a lot harder. There's no way to just swap the OS itself, which means you need to clone the LPAR and then connect the user data volumes, with required catalog tinkering. And SPOOL needs to be backed up and restored (or contents lost). Is this really still true in 2024? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- The information contained in this message is confidential, protected from disclosure and may be legally privileged.
