Like to have some comments on my questions related to FRS and DFRS
We have two Windows Server 2012 R2 Datacenter domain controllers that is still using FRS I guess, since when we use “dcdiag” I get the message “Starting test: DFSREvent: Skip the test because the server is running FRS”. One thing I am wondering about is, why do I get DFSR messages in the event log if the server is not configured to use DFSR. See images below.
Is there anything special I need to consider when migrating from FRS to DFSR. Domain and forest functional level are today Windows Server 2012 R2. Do I need to backup my GPOs for example ? Would the migration have any impact on the users, should I do it outside office hours? As I understand it’s the SYSVOL that is going to be implicated, but if we have many scripts there, and one user tries to login when we are doing the migration, will the script fail ?
I also see DFS and DFSR, is this the same? Just different naming ?
We are later going to replace the domain controllers with Windows Server 2022 Standard, is there anything I need to take into consideration regarding DFRS? Like for example upgrade domain or forest functional level?
I guess the complete guide is here: https://docs.microsoft.com/en-us/windows-server/storage/dfs-replication/migrate-sysvol-to-dfsr .... A lot to read, so I guess using this guide will be ok https://techcommunity.microsoft.com/t5/storage-at-microsoft/streamlined-migration-of-frs-to-dfsr-sysvol/ba-p/425405 think about step “Quick Migration”
Thanks for any reply
