Yes that's correct with CUCM 10.X we've introduced a new feature in regards to authenticated and encrypted modes of the phones. Now you don't need the USB security Tokens to put your cluster into mixed mode or to update the CTL file.
However it's still possible to use "old" method with CTL Client and Secure Tokens, so after upgrade you can continue using your USB Tokens with CTL Plugin to update the CTL files on your cluster.
And the CTL Plugin can still be downloaded from the plugins page of the CUCM.
If at one point you will decide not to use USB Tokens anymore and you would like to go with the "new" method then the only thing you'd need to do would be to run:
utils ctl update CTLFile
followed by the restart of the CCM and TFTP services (this step was the same with the old process as well)
This command will generate the new CTLfile and will sign it with the private key of the CCM+TFTP certificate of the Publisher. Phones will trust the new CTL file cause it's signed by the certificate, that was included in the old CTL file.
Please let me know if you'd need further clarification on this.
If I'm doing the upgrade using the Prime Collaboration Deployment from CUCM 9.1 with the IP address changes - at some point I'll have two CUCM clusters, one with old IPs and two with new IPs. What is the best way to move the phones from one old cluster to the new one? Thanks for your help on this.
