And I can venture an unofficial answer to the licensing portion of the question, I think....
IBM abolished the "Single Version Charge" (SVC) limitation quite some time ago, and both z/OS Version 1 and z/OS Version 2 should have the same license charge. There's a possible bit of daylight if the optional chargeable features/elements vary. For example, certain fonts are now incorporated into the base z/OS operating system, so that might be a minor "win" if applicable. z/OS 2.2 is past its End of Service date, but an optional chargeable Service Extension (defect support only) is still available until September 30, 2023. Commercially speaking I suggest you (your customer) give IBM (and other vendors, if applicable) the opportunity to craft a proposal with an IBM z15 T02 and z/OS 2.5. That might be a more sensible approach commercially and technically rather than "patch and pray." Just to pick a random example, IBM didn't add TLS 1.3 support to z/OS until z/OS 2.4 AT-TLS. And I don't think TLS 1.2 was available until z/OS 2.1 (retrofitted to z/OS 1.13). There are currently known security concerns with TLS prior to 1.2, and maybe 1.3 will eventually/soon be the new minimum secure baseline. - - - - - - - - - - Timothy Sipples I.T.
