[cisco-voip] CUCM 10.5 cluster migration

[Stephen Welsh]

Hi Mike,

One technique some of our customer of PhoneView (http://www.unifiedfx.com/products/phoneview/) do is use one of our built-in macros that bulk updates the TFTP Server to move the phone from one cluster to another.

This page has details on the advanced macros that enable this:

Basically you would send a “Cmd:SetTFTPServer:10.10.10.10” to move the phone(s) to TFTP Server 10.10.10.10
This will enable AltTFTP and set the TFTP Server (it also deletes the ITL File too), you can then later remove the AltTFTP using the “Cmd:ClearTFTPServer”

Kind Regards

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
