Upgrading from end-of-service releases

CICS® TS 3.1, 3.2, 4.1, 4.2, 5.1, 5.2, 5.3, and 5.4 are withdrawn from support. When you upgrade from an end-of-service release, you should follow the same migration process as you do for upgrade from any in-service release, but there are additional migration considerations and actions that are specific to your current end-of-service release.
