325473 How to move a DHCP database, section "Import the DHCP database"

I have an existing 2003 server which is a DC and DNS server. This server hosts all the AD roles. I also have a 2000 server hosting dhcp. I'd like to transfer the database from 2000 to the 2003 server.

In the article http://support.microsoft.com/kb/325473, under the section "Import the DHCP database", it says "...Additionally, if the target Windows 2003 server is a member server, and if you plan to promote it to a domain controller, we suggested that you perform the DHCP database migration before promoting it to a domain controller. Although you can migrate the DHCP database to a Windows 2003 domain controller, the migration to a member server will be easier because of the existence of the local administrator account."

As I mentioned, our 2003 server is already a DC. Does this mean the procedure will not work?

What steps do I need to take?

Thank you,

Yes and No, You still need to do the import steps as described but need to do an additional step first.

If you have a DC already, all the account to the BUILT IN\administrators, login as that user and proceed with the import as detailed in the microsoft link.

You can do this even if your server is already DC. But there is another issue I'm aware of. I think that DHCP database migration from 2000 to 2003 is not possible :/

The only ne way I can remember, is to disable 2000 DHCP server, configure appropriate scope(s) on the new one, recreate all necessary reservations and enable IP conflict detection (value 2 or 3 is enough) for preventing IP address issue. Then DHCP database will be rebulit after some time.

Thank you. The migration worked fine per 325473.
