Hi,
We are migrating from a Single Exchange 2010 sp3 server to a 2-node exchange 2013 DAG cluster, located in another AD site.
I can move a mailbox from 2010 to 2013 without issue, but the WAN link between 2010 and 2013 is very small.
It will take us too long to move all mailboxes with move-mailbox over the line.
Is there another way to move the mailboxes or Databases more quickly?
I was thinking about copying the DB's to a physical disk from 2010 and then move and mount it on 2013. Is that even possible? I explored the possibility to seed the DB to 2013, but don't have the option to do so. 2010 is installed on 2008R2 standard.
We prefer a short downtime and move over everthing in one go as opposed to having coeexistance for longer period of time to allow the move mailbox over the WAN to complete.
Thanks for any suggestions.
