Migrate old 2003 server to a new 2003 server

Hey Guys

I need abit of help

Its been a long time since ive had to do server work and i was wondering if anybody out there could refresh my mind on how i would migrate a old 2003 server to a brand new 2003 server but keep everything. (EG programs, features, files, folders, databases, AD,) Pretty much everything from the old server i need.

Im in no urgent rush for the solution but it would be nice to get it asap

Thanks guys for the input in advannce :)
