# Offline Migration Reference

- **Windows PE.** The ScanState tool can be run from within Windows PE, gathering files and settings from the offline Windows operating system on that machine.
- **Windows.old.** The ScanState tool can gather files and settings from the Windows.old directory. The Windows.old directory is created during Windows installation on a partition that contains a previous installation of Windows. For example, the ScanState tool can run in Windows, gathering files from a previous Windows installation contained in the Windows.old directory.

When you use User State Migration Tool (USMT) to gather and restore user state, offline migration reduces the cost of deployment by:
- **Reducing complexity.** In computer-refresh scenarios, migrations from the Windows.old directory reduce complexity by eliminating the need for the ScanState tool to be run before the operating system is deployed. Also, migrations from the Windows.old directory enable ScanState and LoadState to be run successively.

- **Improving performance.** When USMT runs in an offline Windows Preinstallation Environment (WinPE) environment, it has better access to the hardware resources. Running USMT in WinPE can increase performance on older machines with limited hardware resources and numerous installed software applications.

You can use only one of the `/offline`, `/offlineWinDir`, or `/OfflineWinOld` command-line options at a time. USMT doesn't support using more than one together.
