[cisco-voip] Upgrading to 8.5(1) CUCM

[Lelio Fulgenzi]

There are two sides to this question, licensing and technical. 

Technically speaking, you'll have to look at the CUCM compatibility matrix to see what versions can upgrade to what versions. Cisco hasn't been too bad at making upgrades work especially from an n-1 release, however, there are occasions depending on how far into the N-1 train you venture you will not be able to upgrade to the next release. For example, you can't upgrade from 7.1.5 to 8.0 I believe, but you can upgrade from 7.1.5 to 8.5 (please check the matrix for exacts).

Licensing is another matter and handles the legality of upgrades. An "Essential" contract allows you access to minor upgrades, i.e. N.x to N.y. A UCSS contract allows you access to major upgrades, i.e. N.x to N+1.y. In actuality, you can upgrade to the latest version, not just N+1. ;) 

Hope that helps, I'm sure others will offer up some comments as well.

Hi All,

Is there a roadmap for that? 

Kind Regards
