Possible to have DNS cluster *and* local nameservers?

[electric]

Hello,

I am interested in using the DNS clustering capability of cpanel. However, I also want to allow existing resellers to continue using their "local" nameservers.

For example, let's say we have the following setup:

server1.host.com <-- reseller.com account is located here
primary.DNS_server.com <-- This would be the new primary DNS cluster
secondary.DNS_server.com <-- This would be the new secondary DNS cluster

So we want to have the following:

Existing ns1.reseller.com and ns2.reseller.com nameservers would both be located on the server1.host.com machine. This existing reseller would NOT use the DNS cluster.

New resellers would have their ns1 nameserver created on the primary.DNS_server.com and ns2 nameserver created on secondary.DNS_server.com.

So, my question is:

Is it possible to have BOTH a dns cluster *and* "local" nameservers at the same time?

Thanks.
