Supported Operating Systems
User State Migration Toolkit (USMT) 4.0 does not have any explicit RAM or CPU speed requirements for either the source or destination computers. If your computer complies with the system requirements of the operating system, it also complies with the requirements for USMT. You need an intermediate store location large enough to hold all of the migrated data and settings, and the same amount of hard disk space on the destination computer for the migrated files and settings.
The following table lists the operating systems supported in USMT 4.0.
| Operating Systems | ScanState (source computer) | LoadState (destination computer) |
|---|---|---|
| Windows XP Professional | X | |
| Windows XP Professional x64 Edition | X | |
| 32-bit versions of Windows Vista | X | X |
| 64-bit versions of Windows Vista | X | X |
| 32-bit versions of Windows 7 | X | X |
| 64-bit versions of Windows 7 | X | X |
Note
You can migrate a 32-bit operating system to a 64-bit operating system. However, you cannot migrate a 64-bit operating system to a 32-bit operating system.
USMT 4.0 does not support any of the Windows Server® operating systems, Windows 2000, or any of the starter editions for Windows XP, Windows Vista, or Windows 7. In addition, USMT 4.0 only supports migration from Windows XP with Service Pack 2 or Service Pack 3.
Software Requirements
- Must run in Administrator mode in Windows Vista and Windows 7. When manually running the ScanState and LoadState tools on Windows Vista and Windows 7, you must run them in Administrator mode from an account with administrative credentials to ensure that all specified users are migrated. This is because User Access Control (UAC) is enabled in Windows Vista and Windows 7 by default. To run in this mode, click Start, click All Programs, click Accessories, right-click Command Prompt, click Run as administrator, and then specify your LoadState or ScanState command. If you do not run USMT in Administrator mode, only the user profile that is logged on will be included in the migration.
Important
You must run USMT in Administrator mode from an account with full administrative permissions, including the following privileges:
- SeBackupPrivilege
- SeDebugPrivilege
- SeRestorePrivilege
- SeSecurityPrivilege
- SeTakeOwnership Privilege
Must run from an account with administrative credentials in Windows XP. If you do not run the ScanState tool from an account with administrative credentials when Windows XP is the operating system on the source computer, some operating-system settings will not migrate, such as wallpaper settings, screen-saver selections, modem options, media-player settings, and RAS connection phone-book (.pbk) files and settings.
Specify the /c option and <ErrorControl> settings in the Config.xml file. USMT will fail if it cannot migrate a file or setting, unless you specify the /c option. When you specify the /c option, USMT logs an error each time it encounters a file that is in use that did not migrate, but the migration will not be interrupted. In USMT 4.0, you can specify in the Config.xml file which types of errors should allow the migration to continue, and which should cause the migration to fail. For more information about error reporting, and the <ErrorControl> element, see Config.xml File, Log Files, and XML Elements Library.
Install applications before running the LoadState command. Install all applications on the destination computer before restoring the user state. This ensures that migrated settings are preserved.
Hard-Disk Requirements
Ensure that there is enough available space in the migration-store location and on the source and destination computers. For more information, see Estimate Migration Store Size.
