Active Directory Domain Controller Migration From Server 2003 to Server 2012
A client has a Windows 2003 Server as their AD domain controller. This is the only server on their network.
We have purchased a new Windows 2012 server. The goal is to set this up on the network and have it take over as the AD domain controller. We are not getting rid of the 2003 server right away, but it will be taken down once some applications are installed on the new server.
Can anyone recommend a good checklist or resource of the steps necessary to set up the new 2012 server on the network, replicate the AD from the existing 2013 server, and become the new primary domain controller? Then, anything that should be done with the 2013 server before it's taken off-line.
Any guidance to help make this a smooth transition would be greatly appreciated.

well you can join the 2012 server to the domain then start to move the fsmo roles over and then raise the domain to 2012 when the 2003 server is finally just a member server although if you want to still use it you cannot raise the domain level or it will not work

I performed the set up and migration of the new Windows 2012 server today and the information provided in these answers was perfectly helpful. The only piece that was missing was some information on how to transfer the FSMO roles, but I found that with a quick search and it worked great. Both servers are now running as Domain Controllers on the network, with the new Windows Server 2012 as primary. We'll demote the 2003 server at a later time. (And, once the 2003 server is gone, we'll raise the forest and domain functional on the 2012 server.)
