available from most cable vendors. The Easy Transfer Cable includes circuitry that links two computers using their USB ports and can transfer data at approximately 20 gigabytes (GB) per hour.

Use USMT to migrate user state in high-volume deployment projects . It can execute complex, repeatable migrations of user state data between operating systems . You can script USMT; you can execute it as part of an MDT 2010 Lite Touch Installation (LTI) or Zero Touch Installation (ZTI); or you can execute it directly at the command prompt . In addition to document and settings migration, USMT can migrate application preferences for Microsoft Office applications between versions of Office . For example, USMT can migrate Office XP settings to the Microsoft 2007 Office system . Version 4 .0 is the new version of USMT supporting Windows 7 migrations . It includes numerous changes from USMT 3 .0, but the most notable are:

Hard-link migration store For use in Refresh Computer scenarios only, hard-link migration stores are stored locally on the computer that you re refreshing and can migrate user accounts, files, and settings in less time using far less disk space . Support for offline Windows operating systems You can gather data from an offline Windows operating system using the ScanState command in Windows Preinstallation Environment (Windows PE) . In addition, USMT now supports migrations from previous installations of Windows contained in Windows .old directories . Volume Shadow Copy support With the /vsc command-line option, the ScanState command can now use the Volume Shadow Copy service to capture files that are locked for editing by other applications .

This chapter mostly describes USMT because of its power and flexibility in large-scale migrations . Later in this chapter, you will learn how to plan, develop, and deploy a custom migration project by using USMT .

Microsoft introduced IntelliMirror with Microsoft Windows 2000 so that users data and settings could follow them from computer to computer on the network . For more information about IntelliMirror, see 15, Managing Users and User Data . The following two IntelliMirror features in particular minimize the need to migrate user state when deploying Windows 7 because these features store user state on the network .

Roaming user profiles Roaming user profiles ensure that users data and settings follow them on the network . This feature copies users data and settings to a network server when they log off their computers and then restores their data and settings when they log on to another computer anywhere on the network . This feature provides a transparent way to back up users data and settings to a network server . Folder redirection Folder redirection allows IT professionals to redirect certain folders (My Documents, Application Data, and so on) from the user s computer to a server . This feature protects user data by storing it on a network server, thereby providing centralized storage and administrator-managed backups . When used with roaming user profiles, folder redirection speeds the logon process by removing documents and other large files from the user profile .

than Windows Xp. Therefore, carefully review 15 before you rely on IntelliMirror in any Windows Xp migration project.

Although USMT will generally be used in most enterprise environments, some businesses may find Windows Easy Transfer a simple and useful alternative to using USMT . This section briefly describes the basic functionality of Windows Easy Transfer, which can be particularly useful in bench deployments . Before you use Windows Easy Transfer, check for the following prerequisites:

The destination computer must be running Windows 7 . Windows 7 can create a Windows Easy Transfer data collection disk to execute the data collection portion of the migration on previous versions of Windows, but the destination computer must be running Windows 7 . The source computer can be running any of the following operating systems:
