Heya, Ned here again. I am out of my barrel and on the road again this week, coming to you live from Las Colinas Texas. As you may have noticed, I recently wrote a TechNet Whitepaper on how to migrate your old custom FRS data to DFSR. Hopefully that's been useful.

In the meantime though, Mike Stephens and I also created a free migration tool. Because I am lazy very busy I am simply going to repost from our download page at Code Gallery. I hope you find this useful.


FRS2DFSR is a utility that assists Windows admins in moving from the legacy File Replication Service (FRS) to the 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 operating systems. The 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 the replica set in Active Directory and creates DFS Replication group with the same servers, folders, connections, and settings. See the release notes for utility limitations. This tool is not used for SYSVOL migrations, see below for steps on using DFSRMIG.EXE in that scenario.

Important support information:

This tool is provided as-is, without warranty and is not supported by Microsoft Commericial Technical Support (aka CTS, PSS, CSS, EPS). No official support cases may be opened against this tool. It is intended only as a fully functional sample. Use the Discussions and Issue tracker tabs to report issues.

For a supported set of steps for migrating from FRS to DFSR for custom sets, see:

DFS Operations Guide: Migrating from FRS to DFS Replication

To migrate SYSVOL, use the DFSRMIG.EXE tool included in Windows and reference:

SYSVOL Replication Migration Guide: FRS to DFS Replication
