    Description

      When a MongoDB 4.2 database is downgraded to FCV=4.0, the existing unique indexes in data format 11 and 12 should continue to operate in this format. Create a script that users can run that will identify and rebuild all of these indexes in the older format of 6 and 8.

      Coordinate with docs team regarding publishing of this script.
