In prepping for Windows 7 I decided to take another look at Microsoft’s USMT (User State Migration Tool) to see if it was up to the task of getting users migrated from XP to Windows 7 in fairly short order.
The USMT has been around for awhile and is available from the Automated Installation Kit (AIK).
There is a so-so video available from Microsoft’s Windows 7 page which walks you through using the USMT. It seems fairly simplistic and would probably work for small-to-medium organizations. Note, this is used to migrate user state data only, not for deploying images of Windows 7.
