CM Version Choice

Answered Question
Apr 10th, 2008

Hi,

I've been out of the IPT loop few a couple of years and find myself a little confused as to what version of CM would be recommended for a new install.

My understanding thus far:

4.x - Windows Platform

5.x - Same as 4.x but on Linux

6.x - Same as 5.x (linux only) but with some extra bells and whistles.

Does that sound about right? If so what platform would you go with for a fresh site or does it simply depend on the strategic platform choice?

Many thanks.

I have this problem too.

Hi Doug,

Yes, that pretty well encapsulates things :)

CCM 5.x is based on CCM 4.1(3) and incorporates that feature set (on a Linux platform). CCM 6.x is based on CCM 4.2(3) and incorporates that feature set (on a Linux platform). The latest CCM 4.x release is CCM 4.3(1) built on Windows server 2003.

I think most people here would advocate going straight to CCM 6.1(1)a

Hope this helps!

Great thanks Rob. So in your opinion the favoured platform in the marketplace is erring towards Linux(if strategic platform choice wasn't an issue)? My personal experiences of 3.x and 4.x on a Windows platform was how should I say 'less than enjoyable'. :)

Hi Doug,

Most people seem to find the Linux Appliance version of CCM much easier to work with. Upgrades can be done on "split partitions" so rolling back to the previous version is much quicker. The feature set in CCM 6.x is pretty vast and the 6.1(1) version seems to have most of the Bugs worked out (most ;-)

CCM 4.2 and 5.0 have both been EoL as well;

EoS and EoL for for the Cisco Unified Communications Manager Version 5.0

EOS/EOL for the Cisco Unified CallManager Version 4.2

That being said, CCM 4.2 and 4.3 are very popular as well, but if I were starting a fresh installation I would go with CCM 6.x.
