I am migrating from Exchange 2010 to Exchange 2013 and I have nearly finished the project with much success by following the Microsoft “Exchange Server Deployment Assistant” document. &nbsp; 
 
The 2010 Arbitration mailbox “SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}” has already been moved to the new server. 
 
My two questions are: 
These system mailboxes are still on my Exchange 2010 server. &nbsp;Do I need to move them to the new server?

<li>SystemMailbox{1f05a927-9a22-417a-a3ba-ed0867fc34d0}</li>
</ol>
 
Do I need to keep any of these mailboxes in my Exchange Organization after removing the Exchange 2010 server?
