Understanding of using USMT tool

           USMT (User State Migration Tool) is a set of command-line tools that gives administrators more control over user data migrations.
           You can use USMT in large environments where you need to migrate the data of multiple users on multiple machines. The command-line interface for USMT helps administrators incorporate USMT into enterprise environments and automated processes. USMT uses tools to capture and store user data in the first phase of the migration, and then restore the data to another operating system from the captured data. USMT is included in the Windows Assessment and Deployment Kit (ADK) for Windows 8.1.
