[cisco-voip] CSR 12 Experiences

[Matthew Loraditch]

As partner and participant in the CUWP licensing program, I am technically required to have our internal system on the latest software versions.

We usually update within a month or so of release depending on integration compatibilities.

We’ve since done a few clients as well. I’m not sure what Brandon was referring to with the daredevils comment. The biggest pain for us is and will be the licensing conversion. Finding and converting years of PAK keys into one smart licensing account can be a pain. I will say our installs are fairly simple, BE6K, maybe some UCCX and that’s it.

The actual upgrades have been painless and just the same as any previous ones.

As far as actual phone features goes, I feel like there is just a little bit every time now.  A .0 or a .5 seem to have the same amount of changes. It’s only a historical association that makes folks recoil.  I just did a quick comparison of the 11.5 and 12.0 Release notes and they have nearly the same amount of listed new features/changes.

I'm hoping those of you that have been upgrading to and running CUCM 12.0 can share your experiences here.

What did you learn during the upgrade process?  What issues are you still battling?  What drove you to version 12? What were the pleasant surprises?  Why didn't you upgrade to 12 yet?

Brandon Ta at CLUS 2018 referred to those running 12 already as "daredevils" and while I am generally opposed to deploying .0 releases, CSR 12.5 may still be relatively far out on the horizon.  It would benefit the community if we might share experiences here.

There is not much banter on the Cisco support forums or communities and the release note caveats and bug tracker responses seem generally manageable.  The real life pro tips are always in the comments section though.

Thanks all.
