There is no direct upgrade path from XP to Windows 7 but users can use
the User State Migration Tool (USMT) to migrate user data and
settings. I wrote a piece about the upgrade, with an accompanying
video, at:

However, what do you do if you have a site with hundreds of XP or
Vista users? Is there an available light touch approach?
