MDT 2012 Replace computer task sequence

Hello all,

I am using MDT 2012 Update 1 for upgrading over 200 machines from Windows XP to Windows 7.

Some of these machines are going to be REFRESH scenario. I have the task sequence for REFRESH scenario and it is working as expected.

However, I do not know how to create REPLACE scenario task sequence. From what I understand, I need to create two tasks sequences. I have created a task sequence that capture user's data and upload it to a share.

But how do I create a restore task sequence that restores that data to another computer after installing OS? What do I need to in the restore task sequence that either prompts me to select where to restore the data from or knows where the data is?

In SCCM there is computer association, but I have not been able to figure out how to do it purely using MDT. 

Any expert help is greatly appreciated.

Thanks in advance,
