Hi,
we're currently moving around 400 mailboxes from exchange 2010 to 2013. Setup consists of one exchange 2010 and two exchange 2013 servers. All users migrating have also archive mailbox. The move is about 100MBs per minute and there is only one concurrent request inprogress. All other requests are in queued.
We already changed all parameters regarding MRS service on all CAS servers in exchange organization.
Any idea what could be the problem or limitation?
