I am looking to be pointed in the right direction for migrating my two current DHCP servers (which are each located on a DC...) to 1 DHCP cluster separate from our DCs. This is all coming from and going to be on Windows.

Here is what is going on.

1 DHCP server for one location handing out DHCP for hypothetical subnet 10.1.0.0/255.255.0.0

1 DHCP server for one location handing out DHCP for hypothetical subnet 10.2.0.0/255.255.0.0

I am looking to setup 2 (or 3) new DHCP servers and cluster them for fail-over, and have it setup to do DHCP for both 10.1 and 10.2 networks.

What is the best way for me to go about starting this process?

Can I use the DHCP export/import commands to merge 2 DHCP servers into one, or am I going to have to use the commands for one server and then manually setup the other?

Would it be more appropriate to setup the 2-3 server cluster before beginning the migration or after?

  • Which Windows version is used? Usually you create the failover cluster and then assign the DHCP server role inside the cluster. You should even be able to import your settings.

  • You have two options: 1) create a "real" failover cluster and add the DHCP role 2) use DHCP failover

  • Will there be any issue with the following. DHCP1 on 10.1.0.1, DHCP2, on 10.1.0.2, DHCP 3 on 10.2.0.1, and DHCPCluster on 10.1.0.3?

  • Just export, merge, then add the scope manually, import reservations and things you need from the dump. After that, build a failover-cluster.
