Deleting ITL files when migrating between clusters with same IP Address and Hostame.

[Syed Hussain]

Hello All,

I am in the process of performing a P2V upgrade from CUCM 8.5 to CUCM 9.1.

We will be keeping the same IP address and Hostname on the new cluster.

Do I still need to follow the procedure for Migrating IP Phones Between Clusters with CUCM 8 and ITL Files as per the document in the following link:

Thanks,

Mustafa
