[cisco-voip] CUCM 10.5 cluster migration

[Ryan Ratliff (rratliff)]

Corporate Directory will work with the default settings in 10.4.2, secure EM will not.

If both clusters are up and running you are much better off just adding CallManager.pem from the TFTP server of the new cluster to Certificate Management of the old cluster as  "Phone-sast-trust”.
This will let TVS on the old cluster authenticate the new cluster’s ITL and you don’t need to mess with anything.

It does require that the phones can establish a secure connection to TVS on the old cluster, but if they can’t do that already then they wouldn’t take the rollback parameter change either.

They will register and work, but no SSL functions will work, eg secure Extension mobility or the  corporate directory.

Hi All, I need to move about a 100 phones to a new cluster, and then add an additional 200+ phones. My problem is I want to use the "Prepare Cluster for Rollback to pre-8.0" parameter, but I can't change the option 150 in the DHCP server until the next day. My question is once I set this parameter  and I reset the phones they will register with an empty ITL file, but will the phones still function? If I can reset the phones to clear the existing ITL and have them work the following day I can then change the option 150 to the new cluster and then reset the existing phones and add new phones in.  I know I can lab this up, but wanted to make sure there were no gotchas associated with this method.

Thanks,
Mike
