I would think you would want to drop your DNS record TTLs for all domains being moved to something very low several days before the switch-over period.
More precisely, you want to change the TTL on the NS records, which are in the parent zone. If you're keeping the name but changing the address, worry about the A records, too. --Steven M. Bellovin, http://www.cs.columbia.edu/~smb
