I am not giving any stamp of approval. On several occasions over the last 30 or 40 years, we have run for longer or shorter periods on unsupported versions. Right now, I am actually at a supported (2.3) level. A couple of the unsupported periods were when it was thought the mainframe's days were near to the end. Only once do I remember a problem arising where IBM said, sorry, you are at an unsupported level. And, on that occasion, I did have a sandbox running a supported level where I did reproduce the problem, get a solution which happened to have a PTF for the unsupported level I had in production.
I am also now at the point you are. I and our z/OS will retire together within the year. All applications have moved. Archive and clean-up underway. I pushed for the last upgrade because I knew I would be eliminating ISV products with IBM equivalents and I wanted to at least have support for the targets. Which proved wise. IBM DFRMM support in particular was quite helpful. > -----Original Message----- > From: IBM Mainframe Discussion List <[email protected]> On > Behalf Of McCabe, Ron > Sent: Friday, July 16, 2021 12:52 PM > To: [email protected] > Subject: z/OS versions > > Hello IBM List, > > Got a question about how you feel about running on an unsupported z/OS > version.
