You also want to check all the registries which are superordinate to zones your server is authoritative for, and check that any IP 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.
