Replicate DHCP scope / scope options configuration  from Windows Server 2012 R2 onto another Server

Hi Experts,

We are planning to demote a server running Windows Server 2012 R2 which is also a Domain controller. (i.e removing AD domain services etc and shutting down the server).
This server is also a DHCP server and was wondering if it’s possible to replicate the DHCP scopes configuration and DHCP scope options configuration onto another server? (ie. So that this service is setup on an alternative server so that the DHCP service is not disrupted)

Thanks

Hi,

Yes, You can take a backup of the DHCP server to a location on the server and copy it over to the new server, then after install the DHCP roles you can restore the copied backup on to the new server. - Check the attached JPG.  [Also, there will be a backup already copied in the "C:\Windows\System32\DHCP"].

Also, you can export the command "netsh dhcp server export all " command to export the dhcp settings in a text file and later import it to the new server using the command "netsh dhcp server import all"

You can decommission active directory from server and it will converted to member server and dhcp will remain functional as is if wanted to
Ekse you need to migrate it with netsh tool as mentioned above
Note that when you change server, u also need to change ip helper config on switches as well
