script to copy an drestore user profile data

Hello all,

I am trying to create a script to backup user data. I have a powershell script which works great. But here is the problem, the user name are getting changed as we are moving to new domain. So if I run the script I got it on Internet, it works fine. It back up data to server with username. How I ccan I restore that to new user name. Is there any possibility that a script looks through an excel sheet and match the username and restore the data.

Thanks
