We are planning a major upgrade. We are running CCM4.1(3), Unity 4.0_5, IPCCX 4.0(4) Premium. We are going to upgrade CCM so we can install CER 2.0. As long as were are upgrading we thought about IPCCX 5.x as it gives us some much needed/wanted new options. Should we take the jump to IPCCX 5.X??? Anyone out there running it? Also, as long as we are upgrading we wanted to go to CCM 6.X any thoughts?
