Supported operating systems
The User State Migration Tool (USMT) 10.0 doesn't 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.
|Operating Systems||ScanState (source computer)||LoadState (destination computer)|
|32-bit versions of Windows 7||✔️||✔️|
|64-bit versions of Windows 7||✔️||✔️|
|32-bit versions of Windows 8||✔️||✔️|
|64-bit versions of Windows 8||✔️||✔️|
|32-bit versions of Windows 10||✔️||✔️|
|64-bit versions of Windows 10||✔️||✔️|
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 doesn't support any of the Windows Server® operating systems.
- USMT for Windows 10 shouldn't be used for migrating between previous versions of Windows. USMT for Windows 10 is only meant to migrate to Windows 10 or between Windows 10 versions. For more information about previous releases of the USMT tools, see User State Migration Tool (USMT) overview.
- Must use latest version of Windows PE. For example, to migrate to Windows 10, you'll need Windows PE 5.1. For more info, see What's New in Windows PE.
- Run as administrator When manually running the ScanState and LoadState tools on Windows 7, Windows 8, or Windows 10 you must run them from an elevated command prompt to ensure that all specified users are migrated. If you don't run USMT from an elevated prompt, only the user profile that is logged on will be included in the migration.
To open an elevated command prompt:
- Select Start.
cmdin the search function.
- Depending on the OS you're using, cmd or Command Prompt is displayed.
- Right-click cmd or Command Prompt, and then select Run as administrator.
- If the current user isn't already an administrator, you'll be prompted to enter administrator credentials.
You must run USMT using an account with full administrative permissions, including the following privileges:
- SeBackupPrivilege (Back up files and directories)
- SeDebugPrivilege (Debug programs)
- SeRestorePrivilege (Restore files and directories)
- SeSecurityPrivilege (Manage auditing and security log)
- SeTakeOwnership Privilege (Take ownership of files or other objects)
/c option and <ErrorControl> settings in the
USMT will fail if it can't 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 didn't migrate, but the migration won't be interrupted. In USMT, 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. Installing applications before running the
LoadState.exe command ensures that migrated settings are preserved.
Ensure that there's enough available space in the migration-store location and on the source and destination computers. For more information, see Estimate Migration Store Size.
This documentation assumes that IT professionals using USMT understand command-line tools. The documentation also assumes that IT professionals using USMT to author MigXML rules understand the following concepts:
- The navigation and hierarchy of the Windows registry.
- The files and file types that applications use.
- The methods to extract application and setting information manually from applications created by internal software-development groups and non-Microsoft software publishers.
- XML-authoring basics.
