Two Authoritative servers

[Rodney]

I have switched ISPs and I need to change my domain registration to
reflect the new Name servers. The registry will not change the info
until my new ISP's DNS servers are Authoritative for our domain.
Currently our old ISP is still the Authority for our domain. Can I have
the New ISP make entries in their Name servers as SOA for our domain
and keep the old ISPs entries as the SOA until the domain registry
makes their changes?
