DFS Namespace - what happens with existing DFS Namespaces after moving from FRS to DFSR replication

Hi, what happens with existing DFS Namespaces when migrating from FRS to DFSR replication?

Do I need to change something on existing DFS Namespaces after migration or it will be automatically replicated now using DFSR?
I've found an article that says that after migrating to DFSR replication I need to configure New Replication Group for my existing Namespaces under Replication? Is this true and do I need to configure every new Namespace under New Replication Group?

Hi WW-6729,

As long as you follow the correct migration process, as listed below, all of the namespaces should take care of themselves as part of the process.

Migration Steps:

Prepared State
1. Log in to domain controller as Domain admin or Enterprise Admin
2. Launch PowerShell console
3. Type dfsrmig /setglobalstate 1 and press enter

  1. Type dfsrmig /getmigrationstate to verify all domain controllers have reached a prepared state

Redirected State
1. Log in to domain controller as Domain admin or Enterprise Admin
2. Launch PowerShell console
3. Type dfsrmig /setglobalstate 2 and press enter

  1. Type dfsrmig /getmigrationstate to verify all domain controllers have reached redirected state

Eliminated State
1. Log in to domain controller as Domain admin or Enterprise Admin
2. Launch PowerShell console
3. Type dfsrmig /setglobalstate 3 and press enter

  1. Type dfsrmig /getmigrationstate to verify all domain controllers have reached eliminated state

This completes the migration process and to verify the SYSVOL share, type net share command and enter.

Additionally, be certain in each domain controller FRS service is stopped and disabled. This could occur automatically.

Hi, Thank you LimitlessTechnology-2700!

I can confirm that everything was fine after migrating to DFSR replication. Nothing additional needed to be configured.

Best regards!
