MDT 2012 USMT - How to copy data from additional partition and merge the partitions

Hello,

I am working on migrating few hundred machines from Windows XP to Windows 7. We are using MDT 2012 for this task.

All our Windows XP machines have an extra partition (D: Drive) that has some user data on it. We intend to have only a single partition on all the Windows 7 machines.

I am trying to copy all the data from D drive to a folder on C: drive called Old_D_Drive. After this I intend to recreate the partition using task sequence so that there is only a single partition (C: drive).

How can I accomplish this?

Thanks in advance,
