Thanks Javalenc,

before I rate, could I please have your opinion on this high level plan.

Day1: Install unity 4.0.4 on the new server and integrate with existing Exchange 2003, test to add a user and see if the system works properly. At this stage Exchange 2003 would have 2 Unity 4.0.4 servers connected.

Day2: Run DIRT backup on old server

Day3: Shutdown the old server and do a DIRT restore on the new server.

Day4: Upgrade Exchange to 2007 and then upgrade Unity to 5.x (same day)

Any idea how my plan would change if the Exchange 2007 goes in to a new server.

Thanks

Hi again,

Added another step, think this is better, Any ideas out there? Exchange2007 upgrade will be on a knew server.

Day1: Install unity 4.0.4 on the new server and integrate with existing Exchange 2003, test to add a user and see if the system works properly. At this stage Exchange 2003 would have 2 Unity 4.0.4 servers connected, is this OK?

Day2: Run DIRT backup on old server

Day3: Shutdown the old server and do a DIRT restore on the new server.

Day4: Upgrade Unity to 5.x(still connected to Exchange2003)

Day5: Upgrade Exchange to 2007 on a knew server.

Day5: Run Cisco Unity Message Store Configuration Wizard on unity 5.x and all required steps.
