How can I reset the challenge questions for all user's?

I am needing a way to reset the OAAM challenge questions for all users. I am needing this for 2 reasons.

1. We have new challenge questions to load, which will replace the existing ones in each environment.

2. When we go through our performance testing phase, the group executing this, needs a way to reset back, for multiple runs.

I came across this Doc ID 1270202.1, but that was version 10. This script doesn't seem to exist on version 11gR2.

Restoring from backup is not preferred, because this could take at least a day due to the number of servers. Any suggestions would be beneficial.
