I've been tasked with upgrading a SBS 2003 server to Windows 2012 Standard server. My plan is to add the 2012 server to the existing domain as a member server, then promote it to a domain controller. Now I believe there is something else that is required to make the 2012 box the primary server but I don't know what this might be or what to search for on Microsoft. Can anyone point me in the right direction please?
Also, the exchange part is sorted, as we're planning to move email to exchange online and disable the exchange running on the SBS box.
