I don't see why, and that wouldn't be consistent with what they have done in the past. Some examples: z/OS 2.1 was available September 2013. It was not supported on a z990 or a Z890. Support for those were dropped in 2014 and 2016 z/OS 2.2 was available in 2015. It was not supported on a z9. z9 EC was supported until 2017. z9 BC was supported until 2019. z/OS 2.3 was available in 2017. It was not supported on a z196 (support dropped 2021) or z114 (supported until 2022). z/OS 2.5 was available in 2021. It was not supported on a zEC12 or a zBC12. AFAIK, support for those have not yet been dropped.
I'm not sure, but I think that what IBM has done is to support a level of hardware until the last release of z/OS that is supported on that machine is off support, or at least withdrawn from marketing. Not to support a new release of the operating system on all processors that are currently supported at GA. -- Tom Marchant On Fri, 30 Jun 2023 01:01:21 -0500, Brian Westerman <brian_wester...@syzygyinc.com> wrote: >So is IBM definitely dropping support for the z13s BEFORE z/OS 3.1 is >officially out? If not, then it should be supported by z/OS 3.1. . . . ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
