Good day, (pleaseexcuse my english, its not my mother tongue)

I am in the process of evaluating a domain upgrade. We want to migrate from SBS 2003 to Standard 2008 in the coming months.

I never done a domain migration, i know there is a lot of help on EE, but i also know every migration has its complications and all setups are different.

So here is my Setup:
I only have one Domain Controller with  Windows SBS 2003 SP2, Exchange 2003 SP2, DHCP, DNS and ActiveDirecotry.

My plan is to buy a completely new server, with Windows Standard  2008 and install exchange 2007 on it. This will be come my new Domain Controller.  the Guy before me named the Domain:, so i need to rename the domain back to

I already bought  Microsoft Press Books about  Exchange and 2008, but these might not be the best guides around. EE is usually the best place for advices.

I read about a lot of steps,. and i am a  lot confused so far, like

CALS migration or transition packs from SBS to STD
How to migrate mailboxes. Should i export from 2003, or 2007 will see them and get them automatically?
How About all my user accounts? Do i export AD?

Once the new DC is up, the old one will be flushed.
