Send email reminders to owners for tickets past their due date

With RT 4.0, I had a cron job, running once a day, with a script that
would send an email reminder to owners of tickets past their due date:

0 3 * * * /path/to/

Now that I’m upgrading to 4.2, is there a built-in mechanism to
accomplish this, or do I have to keep using the script?
