Cannot Move user Mail box to another Exchange database which is DAG member

azhar Nasim 0

Moving user mailbox in Exchange Server 2016 DAG Active Database to another Active Database on another member gives following errors

Mailbox migration stops at 95 % giving the below error

Error: MigrationMRSPermanentException : Error: Mailbox changes failed to replicate: Database c0c1dbe-12f4-45b5-8498-51756a2ffc5c doesn’t satisfy the constraint Second Copy because the commit time 11/16/2022 5:00:16 AM isn’t guaranteed by by replication time

One answer was that we have to run this command

Set-mailboxdatabase -identity <target database> -DataMoveReplicationConstraint None

But why we have to run this command and do we have to run this command every time we move mailbox. In my Exchange DAG I cannot move user mailbox from one database to another on all members and getting this error
