Exchange 2013 Move Mailboxes

I am in the middle of a migration from Exchange 2007 to 2013.  By default it only allows you to move 2 mailboxes at a time.

Is there a way to change that to move like 10 at a time?

I found some links online but they all appear to be for Exchange 2010.  Like this one:

Any suggestions?

are you using the wizard?

I'm remiss to think it would force you to manually move 2 boxes at a time.

I recently did a migration myself and i could do more than 2 at a time. I just used the migration wizard in EAC.

can you post the powershell you are using to attempt the migration please?
Mohammed KhawajaManager - Infrastructure:  Information TechnologyCommented:
What is exactly the issue?  If you select more than two, does the migration run and if so, is it running at a reasonable speed.  If speed is the issue and you are on a virtualized environment then you would need to increase the VMBus buffer size.  Refer to Microsoft article on this listed below:
