[cisco-voip] CMM with two CUCM clusters and MGCP

[Ratko Dodevski]

Thanks for your replay 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.

Regards
