How to consolidate microsoft DHCP servers

I have a customer that currently has 2 DHCP servers:

1st DHCP server is Windows 2003, approx 100 scopes, supporting 4500 client PC's and printers.
2nd DHCP server is NT4, approx 100 scopes, supporting 4500 VOIP telephones.

The customer now wants to combine both DHCP servers onto a single, clustered DHCP server, providing the same scopes as before. The cluster side is not the problem.

The problem is how to merge the 2 DHCP databases so as to avoid disruption to the network, especially as this involves data and telephony systems for emergency services (Fire, Police, Ambulance, Hospital, etc - you get the picture).

Hope somebody has some ideas,

Thanks in advance....

Assuming the scopes don't overlap, you should be able to export them from the old servers, then import them into the new one. The import should leave an existing scope alone (can't test it at the moment).
