Transferring accounts and DNS settings

There used to be a nice guide here on how to transfer all domains to a new server and it had as one step to change refresh time for all a records from 14400 to 399

perl -pi.bak -e "s/14400/399/g" *.db

However the system seems to have changed and the .db files no longer have the TTL for all the A records so the comand above no longer helps.

Can anyone tell me where i would change server settings so all TTL settings are set to a lower number than 14400

Thank you

Nobody knows how to change Time To Live server wide?
