Has someone made experiences with the DNS import utility described at http://www.cobaltfaqs.com/index.php?title=DnsImport&redirect=no or know of an alternative.

Above website states that it was used to import DNS from a RaQ4 to a RaQ550. Would it also work for restoring a DNS of a RaQ550 ?

I plan to use Nuonce's backup package which stated that DNS import requires a software called DNSimport, unfortunately they just asked for looking myself at Google, but there are several ones and I'm not sure which really works.
