We are upgrading our CUCM/Connections Clusters to 11.5(1)SU3b and struggling to find the appropriate IM&P version to upgrade to as well.
There is no actual version of 11.5(1)SU3b of IM&P and the release notes for 11.5(1)SU3a states that it has to be installed with CUCM version 11.5(1)SU3a and 11.5(1)SU4 is compatible with 11.5(1)SU4 as well....
Can anyone shed some light on this?
Thanks,
Joe
