Options to migrate mailboxes from Exchange (SBS2003) to Exchange 2010
Posted on 2013-02-07
We are preparing to migrate from a current environment running SBS 2003 to a non-SBS environment that will run 2 servers (1 AD/DNS server and 1 Exchange server).
We are trying to determine the ideal manner in which to transer user's mailboxes from the current server to the new one.
Because this is a new non-SBS domain, we will not be able to join the new Exchange server as part of the new one in order to migrate databases directly.
We have found that exporting to PST; then reimporting to the new server has typically been the most reliable, although long drawn option.
Any thoughts on a faster, but still reliable way of doing this?
Thanks in advance.
