Moving DNS and DHCP to a new 3rd party appliance from Windows 2003!!

Hello,

I have an old 2003 domain (contoso.local) with 2 DCs running DNS and DHCP. The zones are AD integrated. There are around 50 clients on this legacy domain. We want to move DNS and DHCP to QIP so that we can plan to decommission contoso.local.

We've exported all DNS and DHCP records from Windows 2003 to QIP and we're planning to make QIP live for contoso.local, but I have a few questions for removing DNS and DHCP from the 2003 DCs.

Once I've configured QIP to be authoritative for contoso.local and pointed my clients at it, how do I go about removing DNS and DHCP from the 2003 DCs?

  • Is it safe to just stop DNS and DHCP on the DCs for initial testing?
  • Can I move DHCP and DNS one at a time? If this is possible, are there issues with QIP providing DHCP updates, but dynamically registering DNS updated on the 2003 DCs?

To remove

  • Do I need to first change the DNS zone so that it's not AD integrated?
  • Do I need to update the 2003 DCs with SOA and Name Servers on the contoso.local zone to point to QIP?
  • Do I just need to update the NICs on the DCs to point to QIP?

I'm really after a step by step on how to do this, but I'm struggling to find reliable information.
Thanks

    Moving the DHCP technology shouldn't be too difficult, but stripping integrated DNS from active directory not so easy. What are you trying to save? Might be simpler to build out the new domain.

    Hi,
    The long-term plan is to remove the 2003 DCs, but we wanted to migrate the DHCP and DNS components off beforehand. I've got a call with Microsoft next week - it might end up being the case that we migrate the clients to a newer AD domain first as we're unclear of the exact process to follow and so is our support partner who's been brought in to do the work (for anyone thinking of using QIP as a DDI product - think twice...)
