I have a doubt related CUCM version and licensing. My doubt is as follows:
We have a CUCM 6.0.1 Cluster and we want to upgrade to 6.1.4 version. Is it possible to upgrade from the actual version to the commented version without purchase new licenses?
Your DLUs will be fine, but you will need a new feature license for 6.1.
If you have a current UCSS contract, its provided free. If you haven't, it will cost you.
