Migrate SYSVOL to DFSR normally on the remaining Windows Server 2008 R2, Windows Server 2012 R2, and Windows Server 2016 domain controllers. If DFSR data being replicated remains open either on the source or destination, then the file system puts exclusive locks on data being replicated, in that case, data is prevented from staging to thefinal destination (replicated directory) or vice versa. As of today, the source drive contains 829GB of data and the destination drive is currently 899GB with 60GB free. CRESTLINE, Calif.
