I have a client that wants to purchase SBS 2008 but currently has Windows Server 2003 (non sbs) in their environment. They have approx. 40 computers all users setup in Active Directory, DHCP reservation, etc. I know that you can migrate FSMO roles amongst server (non sbs) and everything remains the same. My question is, Is it possible or recommended to migrate from Windows Server 2003 Std to Windows Small Business Server 2008.
