Hi James
Your UCCX system will have references to the CUCM servers for JTAPI, AXL and possibly for NTP.
If you have a look at the Unified CM Configuration in APpAdmin on UCCX, you will have multiple IP addresses for each of those service (except for NTP). If you have multiple AXL service referenced then you should still be able to log in and update the config after the pub has moved. Usually this results in the new IP appearing in 'available' and the old ip lingering in 'selected' so you just swap and save them.
If you do lose the ability to log in, you can use this CLI command to link UCCX back to the new pub for AXL:
set uccx provider ip axl
