If the zone is not Dynamically-Update-able, it should be as simple as changing
the zone definition and reloading (or "reconfig"ing followed by reloading that
particular zone).

If you have Dynamic Update for the zone, then you'll probably want to change
the MNAME field of the SOA record to reflect the new master. You can actually
update an SOA record through Dynamic Update, but it's a little tricky (from
nsupdate, you need to do an "add", and the serial number of the new record must
be higher than that of the old record, otherwise the update will be silently
ignored).
