DFS Migration

Hi, 

I am in need to do a DFS migration from a child domain(windows 2003-FRS ) to another child domain(window 2008 R2 -DFSR)

We have a DFS server and a File server in the windows 2003 child domain.

We have created the new namespace in the 2008 R2 server. 

Kindly let me know how we can migrate DFS links and the file servers to the new DFSR domain. 

Thanks
