USMT migrates a wide variety of data including user files and folders (e.g., the My Documents folder on XP or the Documents folder on Vista), operating system settings (e.g., folder options and wallpaper settings), and application settings (e.g., Microsoft Word settings). For a comprehensive list see “What does USMT 3.0 Migrate?” on the Microsoft TechNet web site at the following URL:

Note: For application settings to migrate successfully, the version of an application should be identical on the source and destination computers. There is one exception. You can migrate Microsoft Office settings from an older version on a source computer to a newer version on a destination computer.
Note: USMT only migrates application settings that have been accessed or modified by the user. Application settings that have not been accessed by the user on the source computer may not migrate.
Note: Some operating system settings, such as fonts, wallpaper, and screen saver settings, are not applied until after a reboot on the destination computer.
