Does anyone know where to find some good documentation on Cisco licenses for UC applications upgrade?
I couldn't find anything from the Cisco websites.
Specifically, I want to know what do i have to purchase for an UCM upgrade from one major version to another on the same or different hardware appliance with or without UCSS?
And for Unity upgrade or migration, can i re-use the FO licenses or user licenses?
Any help is greatly appreciated. Thank you.
