Moving Mailboxes between DAG (between DAG havn't tested Yet)
1. Mailboxes will be offline, since we have to dismount the Database
Sequence of tasks that need to take place:
- Dismount mailbox database on old server
- Run
eseutil /MH NAME.edbto confirm you have a clean shutdown. - Create new mailbox store on New Exchange server and mount it.
- Dismount the new mailbox store
- Manually copy the old database to the new mailbox store database location (make sure it is the same name)
- Run the following command on new server
Set-MailboxDatabase DBNAME -AllowFileRestore:$true - Delete the transaction log files and checkpoint files for that database.
- Mount the store.
- Finally modify user account settings so user access points to the new mailbox server
Get-Mailbox -Database OLD_DB | where {$_ObjectClass -NotMatch '(SystemAttendantMailbox|ExOleDbSystemMailbox)'} | Set-Mailbox -Database NEW_DB
