I am looking to decommision an out of warranty 2003 SP1 server and replace it with a new 2003 SP1 box.  Before removing it from the network, I need to migrate the DHCP database.  Could someone provide steps to perform this change utilizing Microsoft best practices?  

Thanks for any help!

Look in Microsoft's download section ( http://www.microsoft.com/downloads) for DHCPEXIM.

It works.

It worked last year for a migration from NT4 to 2003 (granted, not R2).

De-activate the old server then do
netsh dhcp server dump > dump.txt

from the old server.  That will output a text file detailing all the config. of the server into netsh dhcp commands.

Copy it to the new server, then if necessary search & replace the IP of the dhcp server using notepad to that of the new server then you should be able to import it again with:

netsh /exec dump.txt

Hmm, just read the second link which I had missed... sorry!  It does work... have done it a number of times.

DHCPEXIM works OK, has it's issues but works.  2003 has a few oddities too, mainly around the number 87 (put exactly 87 scopes or reservations on a server and the GUI doesn't work!!)

netsh dhcp ... is really powerful though, quick dump command out and all your config. neatly wrapped up in a text file to re-import when options go missing etc.
