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

[Lelio Fulgenzi]

I just checked, and 6.1 does not have CFUR. If it did, I would have went with your suggestion. Since it doesn't, I would suggest preparing the new cluster to ensure that: (a) all phones that have not yet been migrated have CFUR set to route them to the old cluster, and (b) any non-phone DN that has not yet been migrated can be reached via route patterns. You can use an intercluster trunk for this. If you have enough spare PRIs, register some to the new cluster. Then during a maintenance window you cant temporarily move a PRI over to the new system and test. 

I'm not entirely sure how CMMs are configured and whether the entire blade is looked at as an IOS device or the modules. You may or may not be able to have separate PRI port registered to different clusters. 

Once testing is done, you can simply move your PRIs over. Your migration process will have to remove the CFUR on each phone that is moved over. 

Of course, there are many ways to complete this migration. Take what others say and pick the best that suits your environment. Feel free to post a migration summary, people may have additional comments.

I would keep the CMM registered to the old ccm and route calls to it from the new ccm back to the old ccm. 
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. 

Curious if others have a better idea !

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...
