You need to install the new server as a DC in the existing domain and run the necessary ADPREP commands.  Then transfer the FSMO master roles to the new server, make the new server your Global Catalog (GC) and DNS server, and demote the the existing server.

(The link provided by Jmoody10 will not preserve your user profiles or workstation domain membership - and you cannot "backup and restore" to dissimilar versions of Windows.  You MUST add the new server to the existing domain and then transfer the necessary functionality to the new server and properly remove the old server (or keep it as a redundant AD server)).

This is a more appropriate guide:

However, an upgrade of this nature SHOULD be performed by a professional if you want to get it right the first time.  Otherwise, you have serious risk of creating problems and FAR more work for yourself and disruption to the company.  When you know what you're doing it's easy, when you're trying to follow steps and haven't done this before, it's like performing open heart surgery, if things don't go exactly right and you don't know what to do, your patient (your network) dies.
