FRS to DFSR SYSVOL Migration Steps

Discover the step-by-step procedure for FRS to DFSR SYSVOL migration.

In order to proceed with an  FRS to DFSR SYSVOL migration, the forest function level must be first configured on your Windows server. If your organization has not done this yet, you must first get the forest and domain function level updated.

You can verify if the system uses the FRS using dfsrmig /getglobalstate.

1)    Log in to domain controller as Domain admin or Enterprise Admin
2)    Launch powershell console and type dfsrmig /getglobalstate.

Below output confirms that it has not yet initiated the DFRS migration yet.

FRS to DFSR SYSVOL Migration Steps

Before proceeding with any configuration changes,  we suggest that you familiarize yourself  with the migration stage.

Below are are four states that correspond with the four migration phases.

1)    State 0 – Start
2)    State 1 – Prepared
3)    State 2 – Redirected
4)    State 3 – Eliminated

 

State 0 – Start

With initiating this state, FRS will replicate the SYSVOL folder amongst the domain controllers. It is important to have a current copy of SYSVOL before begins the migration process to avoid any conflicts.

State 1 – Prepared

In this state, FRS continues replicating the SYSVOL folder while DFSR will replicate a copy of SYSVOL folder. It will be located in %SystemRoot%\SYSVOL_DFRS by default. But this SYSVOL will not respond to any other domain controller service requests.

State 2 – Redirected

In this state, the DFSR copy of SYSVOL starts to respond for SYSVOL service requests. FRS will continue the replication of its own SYSVOL copy but will not involve with production SYSVOL replication.

State 3 – Eliminated

In this state, DFS Replication will continue its replication and servicing SYSVOL requests. Windows will delete original SYSVOL folder users by FRS replication and stop the FRS replication.

In order to migrate from FRS to DFSR it must to go from State 1 to State 3. Let’s look into the migration steps in more detail.
