Performance improvements for migration scenarios from Microsoft Exchange 2010/2013 to Microsoft Exchange 2013/2016 and Microsoft Office 365 including tangible overall migration performance improvement
Decreased resource usage on agent host servers and source Exchange servers
Lowered network traffic between MAgE and source Exchange organization during mailbox and calendar synchronization
Processing of a recently added mailbox or deleting a mailbox from a collection is now performed as soon as possible without waiting until processing of other mailboxes in that collection completes.

documents.software.dell.com/.../known-issues

Users will not be able to use Microsoft Outlook to log on to their mailboxes while the Mail Source Agent is processing them within a Remote Users Collection. If a user is working online, Microsoft Outlook will not operate while the mailbox is being processed. After mailbox processing has been completed, a user must log off and log back on to the mailbox.

So request you to please let me know if we should plan and do the copy process after business hours only even if it is Dell Migration Manager 8.12 or 8.13 for Exchange
