Exchange 2013 mailbox migration problem

Suspend/Cancel does not corrupt anything.
Move mailbox doesn't actually move the content, it copies it, then verifies it, before deleting it on the source. Therefore it is completely safe.
As such the first thing I would do is suspend them all. Once the suspension is complete start them off again one at a time.

How do I suspend them?  The command I used to initiate the migration was:

Get-Mailbox -Database <2010 DB> | New-MoveRequest -TargetDatabase <2013 DB> -BatchName "<name>"

I tried suspend-moverequest -identity "user@domain" (for the users with stalled status) and also

get-moverequest -status stalledduetowritecpu | suspend-moverequest

and they both error out.

When you say they error out, what is the error?

When you run get-moverequest does it show the requests?

Simon.

Error is as follows:

[PS] C:\>get-moverequest -movestatus stalledduetowritecpu | suspend-moverequest
Cannot process argument transformation on parameter 'MoveStatus'. Cannot convert value "stalledduetowritecpu" to type
"Microsoft.Exchange.Data.Directory.Recipient.RequestStatus". Error: "Unable to match the identifier name
stalledduetowritecpu to a valid enumerator name.  Specify one of the following enumerator names and try again: None,
Queued, InProgress, AutoSuspended, CompletionInProgress, Synced, Completed, CompletedWithWarning, Suspended, Failed"

    + FullyQualifiedErrorId : ParameterArgumentTransformationError,Get-MoveRequest
    + PSComputerName        : argon.xxx.org

And for one of the stalled users, I get the following, which is confusing because that user still shows as stalled when I run the get-moverequeststatistics command

[PS] C:\>suspend-moverequest -identity "xxx@xxx.org"
You can't modify move request 'xxx'  because it has already completed.

   2 PM] 26F30416,Microsoft.Exchange.Management.RecipientTasks.SuspendMoveRequest
    + PSComputerName        : argon.xxx.org

I just checked the move request status with:

get-moverequest -batchname <name>  and the problem mailboxes show up there as completed, while the output of:

get-moverequeststatistics -moverequestqueue "<name>

shows those mailboxes as stalled.

EMC shows all mailboxes in the correct database.  I still need to migrate mailboxes out of our archive database on the old server, and this fails on each one with the following error:

xxxx@xxx.org,"Mailbox 'xxxx, xxx' has a completed move request associated with it. Before you create a new move request for the mailbox, run the Remove-MoveRequest cmdlet to clear the completed move request.

Running the remove-moverequest cmdlet does clear the mailbox and lets me migrate that user's archive mailbox.  So it appears that the original migration never completed and cleared the move requests, even though all of the mailboxes were migrated?  Is there some way to clear all of the move requests without having to do it for each mailbox?

Thanks, I was able to clear the move requests with that command.
