Sharing a script that I named as Mailbox agent, it is a package of 3 scripts:
1-SubmitMailBoxMoveRequests.ps1
2-ResumeMailBoxMove.ps1
3-ClearCompleteMailBoxMove.ps1
These we used during mailbox moves from old dags to newly created dags for exchange 2010.
update 1-SubmitMailBoxMoveRequests.ps1 script with OLDDAG/NewDAG name
$mbxsrvsrc = “OLDdag01”
$mbxsrvdst = “Newdag01”
Script will check the $countperday value & from each databse migrate the number of malboxes (based on the value) to all destination databases.
Example: If DAGOLD has 4 databases & value for $countperday = 10
than 10 mailboxes from each DB will be migrated to destination databses.
if DAGNEW has 10 databases than 1 mailbox will be moved to db1, 2nd will move to db2 & soon…
Mailboxes will be equally distributed among all destination DBs. (this will be all automatic)
1-SubmitMailBoxMoveRequests.ps1 –> This will submit the requests & suspends after 95% completion
2-ResumeMailBoxMove.ps1 –> This will resume the request based on geography if required, just update the $region.
example: $region = “United Kingdom” (keep its value as * if you don’t want to use region)
3-ClearCompleteMailBoxMove.ps1 –> This will clear the completed requests.
All these scripts will send report in email, so please update the email variables inside the scripts.
$smtpserver =
$from =
$email1 =
Extract the scripts from below link, hopefully these will work for you & will make mailbox moves easy.

you can also filter out the mailboxes that you want to move by updating the submit script, below is the example:
that I used to avoid migration of certain mailboxes & also just migrate the ones above 10 MB quota.
$mbx += get-mailbox -database $db -resultsize $countperday | where{(($_.MailboxMoveStatus -like “None”) -and ($_.Name -notlike “sys*”) -and ($_.ProhibitSendQuota -gt “10 MB”))}
