Search was not working as the configuration was pointing to incorrect old values as a consequence of cloning.


Perform the following local-changes: 
  1. Restore the Pega database with a backup dating from the migration.
  2. Delete the old rulesets from the database using ad-hoc SQL scripts provided by the Pega Global Customer Support.
  3. The search issue is resolved by the solution provided in support article, SA-14326 (
