Active Directory Migration

I have one server (only one!) running 2003 server with Active Directory.  It's an ailing server that needs to be taken out of commission.  What is the best way to migrate Active Directory and all the data to the new server?

    Here's a basic outline of the steps:

    1.  Purchase your new server, install Windows 2003 server as a member server in the same domain.
    2.  Be sure you install DNS and DHCP and, if you are using it, WINS as well as the basic OS.  
    3.  Then run dcpromo to upgrade the new server to a domain controller.  This will replicate all of your Active Directory information.  
    4.  Configure DNS on both servers to be AD-integrated.  This will replicate all of your DNS information to the new server as well.
    5.  Replicate WINS if you are using it from the older server to the new one.
    6.  Either configure a new DHCP scope on the new server, or do a backup and restore of DHCP from the old server to the new one.
    7.  Make your new server a global catalog server.
    8.  Move all of the FSMO roles from the old server to the new one.
    9.  Move/migrate other data and programs from the old server to the new one.
    10. Make sure everything is running smoothly on the new server.
    11.  Either demote the old server and remove it from the domain; or you can keep the old server as a backup and storage server.

    Does Microsoft have any migration tools that will do any of those steps or is is all manual?

    I don't know of any tools for this type of operation. It's not technically a migration, since you are simply installing an additional domain controller into the same domain.
