We have a number of existing customers in production and using IM12.6SP4 for provisioning Mainframe ACF2 R16.
This is a request for adding R16 of ACF2 in the Support matrix or officially list ACF2 R16. as a supported version of CA-ACF2.
Next upgrade is SP8, during 2017 and we will need the same for SP8 and forward.
The old ACF2 endpoint connector works fine and we can also setup and verify the V2 connector if it helps.
