Consolidating multiple DHCP servers RRS feed

  • Question

  • Hello,

    I'm considering consolidating scopes from 70+ servers (AD authorized) to a failover cluster, comprised by a two Windows Server 2016 servers.

    New DHCP cluster would be located in our new datacenter.

    Current individual DHCP servers are located on small sites, all over the world. Server OSes range from 2008RTM to 2012R2. No previous failover partnerships exist between current 2012 servers. I don't know if there's any split-scope relationships between older 2008 servers.

    My high level plan is to migrate all scopes, scope options + leases from the current DHCP servers to my new DHCP failover cluster and ramp down old servers.

    I would kindly ask for your advise, do you see any obvious showstoppers/pitfalls on my high level plan that could be a
    problem? Our network team said it's doable from their perspective. Number of DHCP servers is a bit overwhelming, but I believe that with proper planning I'll succeed.

    Thank you already for sharing your experience.

    I think it is feasible.

     Split scopes cannot be consolidated from two servers and server options that conflict will fail to import.

    There is a article about Migrating DHCP Scopes:
