Thanks for your replay <span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">Pavan. Yes this is one possible scenario but the migration of users is completely random so I cannot determine some pattern and to make those DNs to be routed to the new cluster. Plus, when the migration of the users is complete we need to shutdown old cucm so I then I would have to register the CMM modules on the new CUCM and this means some downtime and reconfigurations.</span><div>

Inbound calls from cmm need to be routed to the new ccm from the old one based on some characteristic of your 150 user batch or by using cfur on old ucm.<br>

Curious if others have a better idea !<br>

> Hi, I have a bit of a problem... I have a customer that migrates from CUCM 6.1 (two server cluster) to CUCM 8.6 (two VM cluster). They have two CMM line cards registered with the old CUCM cluster using MGCP. Now I have to do a migration of users/devices to the new cluster in several phases (150 users per phase) and they will be using the same numbering plan on both clusters. My problem is how to register the CMM modules on both clusters and how to manage the incoming calls when both clusters will have the same numbering plan...<br>
