Beginning with Windows Server 2012, you can easily export and re-import DHCP settings. Cloning or migrating DHCP servers is a snap. The example below exports the settings from \\ORIGDHCP and imports them into the local DHCP Server:
Export-DHCPServer -File "$env:temp\dhcpsettings.xml" -Computername ORIGDHCP Import-DHCPServer -File "$env:temp\dhcpsettings.xml"
