I need to migrate an SBS 2003 DC and Exchange Server to 2003 Server Standard.
Its currently 1 server and BES, The new setup will be 1 DC, 1 Exchange and 1 BES, all 2003 Server Standard.
My dilemma is how to split this task up. I already have the servers built so I’m wondering if I create a trust between the SBS domain and the new domain, will I be able to migrate users to the new domain and still have the ability for them to use the exchange server that is onthe SBS domain so that this way I can move the mailboxes later.
I don’t have a lot of experience with Trusts so I need some clarification if it would be possible to use an exchange server that is on a trusted domain.
