Concern over mixing the release levels of ACF2 for z/OS and the ACF2/CICS interface.
Is ACF2/CICS R15 compatible with ACF2/MVS R16?
Is ACF2/MVS R15 compatible with ACF2/CICS R16?
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.
