I currently have one Windows 2003 Server acting as an active directory domain controller for 15 users/pcs. I would like to add a SBS 2011 server to the domain as the primary domain controller. I need to keep the 2003 server in place because it is hosting an oracle DB that is supported by a third party. Is this possible to do? Would it be considered a migration? Anyone know where I might find the steps to do this?
