Export and import DHCP settings with netsh

Sometimes you will have to transfer DHCP settings via netsh command. This could be useful for a couple of reasons and it is fine to know how to approach it. Anyway, this is the quickest way to do a DHCP migration.
First you have to login to source server (it could be also a failover clustered DHCP service) and open CMD as Administrator. Then you have to enter in netsh mode with typing:
netsh
Now you have to select server with typing:
dns server \\servername
Where servername is the name of the old DHCP server or clustered service name. This will connect you to DHCP server and you are ready to export settings with this command:
export filename all        to export the entire configuration or
export filename 192.168.222.0    to export only a scope configuration (in my case 192.168.222.0)
Of course, you have to replace the filename with full path and name of the file where you want to save exported data. This file now must be transferred to target – new server and we are ready to import the configuration. Of course, priory you import the configuration, the new server has to be authorized in AD. To begin an import procedure, we have to do the same steps as on the old server; open command prompt, enter into netsh mode and select DHCP server. After this, we have just a step to import settings with this command:
Import filename all        to import all settings or
Import filename 192.168.222.0    to import just a scope
That’s all. Just be sure to double-check if the import did its job, disable and unautorize the old server (you can do it also with netsh: netsh dhcp delete server ServerIP). Of course, don’t forget to uninstall the service on the old computer.
You have finished. Good work!
