Hi Justin, During any CUCM upgrade with UCCX (regardless of whether you’re using PCD or not) there is some time where CUCM will probably be on a higher and incompatible version with UCCX. This is expected, we just recommend you reduce the amount of time the two are incompatible, or at least plan for calls to fail until UCCX is upgraded to become compatible. The UCCX upgrade or switch-version process does not check the compatibility with CUCM or the CUCM version.
I think the CCX piece of your upgrade / migration plan below looks good.
