"dig +noall +norec +authority zone @parent" should return you the referral.
e.g.
dig +noall +authority +norec ilap.ca @sns-pb.isc.org
Also it is bad form to turn off the service before the re-delegation
has taken place and the old NS/A/AAAA/DS/DNSKEY records have expired
from caches. The old servers should be slaves of the new servers.
This allows for a smooth transition to occur.
