FRS2DFSR is a utility that assists Windows admins in moving from legacy File Replication Service (FRS) to newer Distributed File System Replication (DFSR) service. Because FRS is no longer supported except for SYSVOL starting in Windows Server 2008 R2 and because Windows 2000 support ends on July 13 2010, this utility can help unblock admins from migrating to newer OSs. Tool is written in C# .NET and can be run on x64 and x86 Windows Server 2003/2008/2008 R2 and Windows Vista/7 with DFSR RSAT installed. It requires domain admin rights and is command-line only. FRS2DFSR.EXE exports an existing File Replication Service replica set, deletes replica set in Active Directory and creates DFS Replication group with same servers, folders, connections, and settings. This tool isn't used for SYSVOL migrations.
