Does anyone know the link that talks about upgrading from CUCM on UCS 8.x to 8.6? I have done upgrades and migration but never on an existing UCS to UCS.
Basically, my question involves the OVA template. When the original install was done, it was installed using the OVA template for CUCM 8.0. Now we need to upgrade them to 8.6. Does anyone know the steps involved and is it documented any where? Do I need to download a NEW OVA template for 8.6 for the upgraded version or is it a straight upgrade from 8.0 to 8.6?
