Hi, We are looking to upgrade our network currently running 2008 R2 Domain Controllers to 2016 DC's
When attempting to promote a 2016 server to Domain Controller status during the prerequisites check we receive the following warning.
"The File Replication Service (FRS) is deprecated. To continue replicating the SYSVOL folder, you should migrate to DFS Replication by using the DFSRMIG command. If you continue to use FRS for SYSVOL replication in this domain, you might not be able to add domain controllers running a future version of Windows Server."
I know we can go through the sysvol migration process to DFRS but what would happen if we don't. Will the contents of sysvol continue to replicate as before whilst using 2016 as our DC's? Can we expect any issues when the last of the 2008 DC's are decommissioned?
