I am hoping someone has some advice on how to handle migrating some mailboxes cross-forest from 2010 to 2013 that has Litigation Hold enabled. From what I understand is it will migrate with Litigation Hold remaining enabled when migrating to Office 365 but how about an On-Premises 2013 installation?
The other issue I have is these mailboxes are large. 12gig, 17gig, 22Gig. I saw migration fail for mailboxes that were only several Gig due to network and/or server resources. I am thinking I would do an Export to archive all the recoverable items and maintain that and then migrate the mailbox and make sure it is on Litigation Hold in the new forest.
Anyone have any suggestions?
Thank you,
Jeff
