These two essays by R. Barry Freundel, R. Marc Angel and R. Avi Weiss (the last two collaborated) about the RCA conversion plan are worth reading: link
Very important statement by R. Freundel:
It is important to emphasize that nothing in this system is designed to change anyone’s previous status as a convert. Those who went through a legitimate process are still Jewish and the regional courts are not charged under this system with reviewing or examining any of these past conversions. Those who are concerned about whether or not they will be accepted in other Jewish communities should consult with their synagogue rabbi as to how they should proceed.
