We are running Exchange 5.5 on Unity 4.0(3). Is it possible to upgrade to Exchange 2000 / Exchange 2003 without affecting anything on Unity?
Note - Exchange 5.5 is on the same box as Unity 4.0(30, but the Unity server is a member of our company domain. i.e. AD is integrated.
Take a look at the following link.
It referecnces Unity 3.1, but the concepts apply to later versions as well.
Hope this helps.
Are you running unified messaging or voicemail only? If unified messaging, Exchange must be on a seperate server. If voicemail only, you can upgrade to Exchange 2000/2003. However, Exchange 2003 requires Unity 4.0(5). It might be a good time to think about upgrading Unity as well. See the Reconfiguration and Upgrade guide below for Exchange upgrade steps.
Hope this helps. If so, please rate the post.
