Migrate DHCP Server from 2008 R2 to 2012 R2

I have two DHCP servers. Primary and Secondary . Both are independent running Primary and Split Scope Scenario. As they are independent followed the same procedure on both the servers.

Login to 2008 R2 DHCP server. Take a Backup. Place it on a location.

It got Exported Successfully.Copied the data. Backed up to my file server

As it wanted to Retain same name and IP. I have unauthorized the DHCP server.

Shutdown the server.

Say yes.

Removing Authorization this Server from the directory will cause the DHCP server to stop responding to client requests.

  1. How can we migrate the DHCP to a different server ? The new server will not have same as the old server.
    That is, Migrate from SRV1 to SRV2.
