The wizards in the File Server Migration Toolkit use Distributed File System (DFS) to maintain Universal Naming Convention (UNC) paths and to simplify the consolidation and migration process.
Many organizations today are consolidating older file servers to reduce the cost of managing multiple file servers and to increase the efficiency of storage allocation and backup tasks. When organizations migrate data to file servers running Windows Server® 2003 and Windows Server 2008, they can take advantage of new features, such as Shadow Copies for Shared Folders and the Volume Shadow Copy service, and enhancements to other technologies, such as Distributed File System (DFS).
