Windows 2003 Migration of active directory

I work for a small school district and have purchased a new server along with Windows 2003 Server Standard Edition R2. My current situation has one server(windows 2000 Advanced Server) as the DC running, AD, DNS, DHCP, file and
print server. I only want to move AD to the new server. I know I should do more.

What is the best method to go about doing this upgrade?

Any suggestions would be great!
