We are planning to upgrade CUCM 6.1 to 7.1(5) in coming weeks and we got the version 7 node license already. I just read a couple of articles about new Cisco UCL (user connection license). They all say CUCM 7.1(5) support UCL only. Should our current node license and DLU be converted to UCL for a sucessful upgrading? Does it mean the CUCM 7.1(5) will stop working if we don't have UCL license?
Thanks in advance.
