I would recommend this mihration guide from EE member MPECSInc: http://blog.mpecsinc.ca/2009/06/sbs-2003-to-sbs-2008-migration-guide.html

i have used it now several times with 100% success rate.
Just make sure you follow the guide step by step making sure that when you run the tests on the SBS2003 server prior to migration that you fix anything it highlights before you proceed.

And ALLWAYS take a GOOD BACKUP nefore you start that includes the SYSTEM STATE
As pointed out, there are 3 good migration methods, but you say the new server already has SBS 2008 installed?   How many workstations?
If you have already started up the new server and completed the few steps that are part of that, then you have a new domain.
If you have just a few number of workstations, then you can just disjoin them from the SBS 2003 domain, recreate the user accounts on the SBS 2008 server, then rejoin the workstations to the new SBS domain.  You can copy files to the new server using a portable USB drive.  And you can export mail to .pst files and reimport them to the new SBS Exchange Server
If you wish to perform a true migration, so that workstations are unaffected and the domain does not change, you will have to flatten the SBS 2008 server and do a reinstall using one of the 3 methodologies listed above.
