SYSVOL Migration Series: Part 1 - Introduction to the SYSVOL migration process

The File Replication Service (FRS) is used for replicating the contents of the SYSVOL share between Windows domain controllers. However, Windows Server 2008 domain controllers, which are operating in the Windows Server 2008 domain functional level, can use the DFS Replication service for replicating the contents of the SYSVOL share. A new Windows Server 2008 feature makes it possible for administrators to migrate replication of the SYSVOL share from FRS to the more reliable and efficient DFS Replication service.

This series of blog posts describe the procedure for migrating the replication of the SYSVOL share on Windows Server 2008 domain controllers from FRS replication to the DFS Replication service.

Why migrate? The DFS Replication service offers several advantages over the older File Replication Service (FRS). Some of the advantages that accrue from using the DFS Replication service are:

a) Efficient, scalable and reliable file replication protocol which has been tested extensively to ensure data consistency in multi-master replication scenarios.
b) Differential replication of changes to files using the Remote Differential Compression (RDC) algorithm, which enhances efficiency in branch office scenarios.
c) Flexible scheduling and bandwidth throttling mechanisms.
d) Self-heals from USN journal wraps and database corruptions – end user intervention and monitoring requirement is minimal.
e) Provides a new UI management tool (MMC snap-in) for ease of administration.
f)  Provides built in health monitoring tools for ease of monitoring deployments.
g) Improved support for Read Only Domain Controllers.

It is hence highly recommended that customers migrate replication of the SYSVOL share to the DFS Replication service.
