I've created a custom function which creates a new Potential from a Potential which is expiring.  I need the function to also duplicate the Contact Roles (those contacts).

Contact Roles seems odd - like it is a separate module from the Potential, but getRelatedRecords does not list that as a supported module.

How can I associate the contacts in the Contact Roles portion of the cloned opportunity?

I'm afraid if I create a new contact record I will be simply duplicating contacts in the system, and not associating an existing contact with the Contact Role.
