Hi Mark,

We have not done this with CUCM but we have done this with CUC which is the same

platform

Shut down your current build on the 7835;

utils system shutdown

Insert the CUCM 7.0(2) install media and restart the box. It should see the

DVD and start the install over again and offer you the  Windows migration option.

Import Windows Data

This option allows you to import database information from a Cisco Unified Communications Manager 4.x system by using a file that the Data Migration Assistant (DMA) tool produces.

Upgrading the First Cisco Unified Communications Manager Node

When you choose Windows Upgrade, the installation wizard prompts you for the location of the preexisting Windows configuration information that the Data Migration Assistant (DMA) tool created. See the Data Migration Assistant User Guide for more information on the DMA tool.

Step 1 - In the Windows Upgrade window, import data from a Windows version of Cisco Unified Communications Manager by choosing Yes

Hope this helps!
