You also want to check all the registries which are superordinate

addresses stored in those registries for your nameserver are
updated, otherwise you will experience either immediate or future
glue madness.
A conservative approach to this kind of transition is to arrange
for your nameserver (or different nameservers hosting the same
data) to respond on both the old and new addresses, and to continue
in that mode until you see no queries directed at the old address
for some safe-seeming interval (bearing in mind TTLs and cached
records, alluded to by Steven and Sam).
If you have access customers (Dial/Broadband/etc) make sure they know
the IP for your DNS server is changing incase they hardcode IP of
your DNS server into their PCs.
