Use the z/OS workflow for migration. See the z/OS 2.4 documentation for ZOS/MF. It will point you to a GITHUB repository that the workflow can be downloaded from. IBM has in the past published "Migration" manuals. As of z/OS 2.4, the "Migration" manuals will no longer be published. Historically, this has been divided into: (A)Things to do before the 1st IPL of (new zos level) (B)Things to do at implementation (C)Things to do post-implementation.
The basic design of a sysplex has the requirement that anything can run anywhere within the sysplex. Many installations do not use this philosophy and have various sub-divisions of the concept. That being said, there is nothing special about this process. Step1 - Install compatibility/fallback maintenance on your existing system (A) Step2 - Upgrade all ISV products to the necessary support level (A) Step3 - Perform the pre-implementation tasks. These are described in the Migration/Workflow as "Things to do before the 1st IPL of (new zos level) (A) Step4 - Upgrade 1 LPAR to the new level, validate and place into production (B) Wash, rinse, repeat. Step5 - Cleanup/Finalize. (C) Step6 - Exploit new function (C) HTH, -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Mohamed Gomaa Sent: Wednesday, February 19, 2020 2:02 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Rolling Z/OS migration [CAUTION: This Email is from outside the Organization.
