We are elimiating our current partner exchange server and will be using a new 2007 Exchange server. 

Unity 4.2

Current Exchange Server - 2003

New Exchange Server - 2007

We have a single Unity server located in Location A (current partner server is in Location A) and the new parter server (Exchange 2007) will reside in Location B.

What tasks need to be completed on the Unity Server?

What tasks need to be completed on the new Exchange Server?

Any other tasks or requirements?

What is the expected downtime for this? 

Any other tips?

I'm afraid you cannot do that, you need at least Unity 5 to support Exchange 2007 as the partner Exchange

Exchange Requirements—Message Store

Exchange Requirements—Message Store

Also make sure you meet this requirements:

Physical Placement and Network Infrastructure

Every Exchange server on which mailboxes for that Cisco Unity server are homed. If Cisco Unity is separated by a WAN from an Exchange server on which subscriber mailboxes are homed, a second Cisco Unity server must be co-located with the remote Exchange server.

Connect the Cisco Unity server and the servers that Cisco Unity relies on with a high-speed switched gigabit network with no congestion. Total MAPI response time must be less that 10 milliseconds.

The Cisco Unity server should be installed into the same Windows site as the Exchange servers it services.

Once you're on 5.X follow this instructions:

We might be moving it to another 2003 server now.  What is the process for this?
