      Description

      New format unique indexes would be initially gated by a variable. Start using FCV to enable or disable new format unique indexes:

      • Plug-in new format indexes into upgrade/downgrade infratructure.
      • Setting FCV=4.2 will cause all exisinting unique indexes to be updated to new format. The content of indexes will not change. New entries will be in new format.
      • With FCV=4.0, existing new format index will remain in this format. Any new unique indexes will be created in old V2 format.
      • Enhance multiVersion test for collectionsPendingDrop.
