Migrate a POP3 server to Exchange 2007 without any down time
Posted on 2008-10-27
I need to migrate an existing POP3 mail server to a brand new Exchange Server 2007 server without any down time. The users should be able to access their e-mail from the old POP3 server if their Outlook settings point to that server, and when I get to their computer and change their settings to point to the new Exchange Server 2007, they should be able to access all their mail from the new Exchange 2007 server. When I have finally cut over all 200 users, I should be able to simply shut the POP3 server off. Is this possible, and if so, how would I accomplish it?
