Migrate DHCP from one Windows Server to another Windows Server

Log on to the old/existing DHCP server.
Open CMD and type command
 

netsh dhcp server export C:\Users\%username%\Desktop\dhcp.txt all

 

 

Log on to the new DHCP server.
Install the DHCP role on the new DHCP server.
Verify that the DHCP service is installed and started on the new DHCP server.
Copy the exported DHCP text file to the new DHCP server.

Open CMD and type command

netsh dhcp server import C:\Users\%username%\Desktop\dhcp.txt all
 

 

Authorize new DHCP server in Active Directory.
Stop or uninstall DHCP role on the old DHCP server.

Note:
If your old DHCP server is in the same network/subnet as the new DHCP server, you will notice that the old DHCP server has been de-authorized automatically. This is to prevent two DHCP servers from handing out conflicting addresses.
