We currently have both CUCM and Unity Connection systems running on the 8.5 version. We are starting to plan to move both systems to 9.1, we found the Cisco License Count Utility (UCT) tool that helps you plan for migrating your CUCM licensing from the DLU model in 8.5 to the UCL or CUWL model with ELM in 9.1. Does anyone have any information on how this transition works for Unity Connection licenses. we currently have close to 850 mailbox licenses on Unity Connection that we would like to merge into the CUWL licensing model post upgrade, but we aren't sure how the transition works.
Thanks,
