The DFSRMIG.EXE /GetMigrationState command generates the following output for all Windows Server 2019 domain controllers: Dfsrmig /getmigrationstate For more information, see Troubleshooting Active Directory Replication Problems. I just sanity-checked. DFSR has many advantages over FRS, including being far more efficient in the data it replicates. Event logs on each show the following events: For customers looking to address these risks and improve visibility into critical replication processes without migrating everything to Azure, Resilio Connect is a comprehensive solution. When relying on DFS-R and its algorithms for mission-critical replication, this lack of visibility can be extremely frustrating for administrators tasked with keeping these critical services operational and users happy. Since the data already exists in the replicated folder, some time will still be required for data staging, building hash and store in the DFSR database. I can run Get-WmiObject -computername computername -Namespace "root\MicrosoftDFS" -Query "SELECT * FROM DfsrReplicatedFolderInfo". Event ID: 4206. so I increased the size of theConflicts and Deleted on both partners. The most commonly used are the ones mentioned earlier.
