Concern over mixing the Release Levels of ACF2 for z/OS and the ACF2/CICS interface.
Is ACF2/CICS Release 15.0 compatible with ACF2/MVS Release 16.0?
Is ACF2/MVS Release 15.0 compatible with ACF2/CICS Release 16.0?
With all previous Releases of ACF2, the ACF2 Base (ACF2/MVS) and ACF2/CICS (CICS interface for ACF2) are compatible with each other. But due to enhancements regarding the AES 256 password encryption, or AES2 in ACF2 terms, the base ACF2 for z/OS release 16.0 needs to be converted either first, or at the same time as the ACF2/CICS interface. Do not do the ACF2/CICS interface first by itself.
Broadcom Support does not recommend you run in this method permanently with different Releases on ACF2. The reason is that many of the ACF2/CICS fixes have two parts. One part goes on the ACF2/CICS interface component, and the other goes on the ACF2 base component. So if you have a problem, you might only be putting on half of the fix if the Releases are different.
