Right now I have 2 cashubs and 2 mailbox servers. &nbsp;Lets call the old domain olddomain.com . &nbsp;We have a new domain lets call that newdomain.com. &nbsp;newdomain.com has the same users and passwords as olddomain.com.<br />
<br />
olddomain.com accepts mail for newdomain.com . &nbsp;<br />
<br />
We would now like to move exchange 2010 from olddomain.com to newdomain.com . &nbsp;The only way I see this possible is by installing exchange 2010 in the same configuration we have now in newdomain.com . &nbsp;Then either doing pst moves or a new move request. &nbsp;The PST method doesnt appear that it would complete in a weekend. &nbsp;So Im left with doing a cross domain mailbox move.<br />
<br />
From reading some articles I would first setup the exchange environment in newdomain.com. &nbsp;<br />
Then I should create a send connector to find mailboxes not currently on olddomain.com to redirect to newdomain.com??<br />
now would I just start to do the new mailbox moves?<br />
anything else?

Exchange 2010 Cross Forrest Migration

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers
