I am not able to find out any specific document but in case there is a
upgrade from CUCM 7.1.3 to CUCM 10.0 from MCS to UCS than the process should be
as similar as upgrade to CUCM 9.1, As per my understand the path should be:
Upgrade CUCM 7.1.3 to CUCM 7.1.5( same MCS)--> Take DRS backup --> Create
VM in UCS on 7.1.5 & restore the CUCM 7.1.5 on that VM--> Upgrade the VM
from CUCM 7.1.5 to 10.0 ( direct upgrade I think we defiantly require from COP
file for the same) --> take the DRS backup of updated VM --> recreate the
VM image on UCS as per CUCM 10.0 OVA template & restore the DRS backup on
this new image
Please correct me if I am wrong?
One more question: in case in older version I have 1 Pub and 1 Sub and 2
TFTP+MOH server and in new UCS I want to have 1 Publisher and 2 Subscribers and
2 TFTP+MOH server than I think I should add the new subscriber after the
Any document on this will be very helpful.
