CCM / Unity Upgrade

I need to upgrade 2 callmanagers and a unity server from ;

CM version 3.3 - 4.1(3)

Unity Version 3 - 4

DO I need to do CM first or unity? I have the upgrade guides but is there any thing else I should be aware of when doing these upgrades.

Thanks

Re: CCM / Unity Upgrade

I would suggest upgrading Unity first and validating that it works with CCM 3.3, then I upgrade the CCM. The Unity-CCM integration configuration in CCM 4.1 is little different, utilizing Line Groups and Hunt Lists instead of call forwarding. The upgrade should take care of it, but in case it does not work here is a good link
