Windows XP Migration Facilities
In addition to the upgrade option during installation, Windows XP also includes two tools that will prove useful for those seeking to install XP who may not be able to upgrade directly, or whose upgrades produce less than stellar results:
The File and Settings Transfer Wizard is aimed at small office and home users who want to migrate files, preferences, and settings from one desktop to another. See Microsoft's "Step-by-Step Guide to Migrating Files and Settings" at www.microsoft.com/windowsxp/pro/techinfo/deployment/filesettings/default.asp for more information on this topic.
The User State Migration Tool (USMT) is the tool of choice for corporate environments. See Microsoft's "User State Migration in Windows XP" at www.microsoft.com/windowsxp/pro/techinfo/deployment/userstate/default.asp for the details.
