Tags: Proceedings, SHARE DC 2025, 2025

Whether you have upgraded to z/OS 3.1 already or are considering it, this session may be valuable to you. When upgrading to z/OS 3.1, or if you are waiting for z/OS Next, it's necessary to understand intended changes in functional behavior which were introduced in z/OS 3.1 and V2R5 including post-GA enhancements and other APARs. This presentation will focus on the findings on z/OS 3.1 and share with you “lessons learned” as well as “hints and tips”. After attending this session, enhancements and behavioral changes observed in z/OS 3.1 or later will no longer be a mystery and your deployment of new z/OS should be much smoother.
