I see, then you might need to look if netsh can do the job:

Force blows everything existing on the new 2008r2 server away.

I haven`t tried this myself, but I see that the Import-SmigServerSetting has a -Force parameter which is described like this:
-Force []
Specifies that imported settings overwrite existing Windows feature settings on the destination computer. If th
is parameter is not used, by default, existing Windows feature settings on the destination computer are preserv
ed.

We are undergoing a DHCP consolidation project. The scope of this project is to consolidate all DHCP servers from around 20 physical servers running around 40 or so scopes into 2 virtual servers. All of the 20 physical servers are running 2003 X86 and our goal is to make the new DHCP servers run server 2008r2. In my lab I’ve followed the steps above. The moment i try to import the 2nd 2003 DHCP server into the new 2008r2 DHCP server, it does not allow me to do this. Is there a way that i can tell the import process to ignore scopes currently running on the new 2008r2 server?

Yes, leases/reservations get migrated. When you stop the source server and start the destination server the clients will operate as normal with existing leases against the new server.

Good luck!

Yes, with an elevated account with domain admin rights.

Eventually the IMPORT command completed (not sure what made it suddenly work), DHCP feature was installed successfully. DHCP Server Service was not started, but now I cannot authorize the new targeted DHCP server in my test lab because there is no Enterprise Admin group on this one DC (replica of a child DC) – so I am making progress, but getting stuck along the way – makes me nervous for when I have to do this across our Production environemnt, globally – starting next week! yikes!

Will all existing leases/reservations etc all get migrated to the target server? What happens to the clients when the source server DHCP Service is stopped?

Yes, the command will install the DHCP Server Role.
You`re running PowerShell with elevated permissions (Run As Administrator)?

Great article – very helpful.

Am having some trouble at the end step: after copying the exported database to the target server, and trying to import the database through the Powershell interface, the powershell.exe bombs out everytime.

I have restarted both source and target machines without luck. Both new builds winth Win2008 R2 Std x64. The import path is definitely correct in the command.

Both machines have static IPs. DHCP Server service is stopped and disabled now on source machine (domain controller), but now I cannot log into the DC (No logon servers available to service this logon request)

PS: Please confirm that the IMPORT-SMIGSERVERSETTING command will install the DHCP Server Role to the target server, upon importing the database?

Help…

Thanks
