Classification: Confidential I disagree on the z/OS upgrade. At the 90,000 foot level, just point to a new sysres and IPL. That’s it. (been doing this for years). Of course, accommodating the necessary changes in parmlib, etc. is a whole additional subject.

HTH, -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Phil Smith III Sent: Tuesday, September 3, 2024 10:20 AM To: [email protected] Subject: Upgrading z/OS vs. z/VM [CAUTION: This Email is from outside the Organization. Unless you trust the sender, Don’t click links or open attachments as it may be a Phishing email, which can steal your Information and compromise your Computer.] I'm NOT trying to start a war here, just trying to grok whether I'm confused or not. 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 ::DISCLAIMER:: ________________________________ The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
