IS-IH Migration script runs for long and does not complete

SA-69131

Summary



Interaction Services (IS)-Interaction History (IH) Migration script is running for a long time.

The below query runs for more than two hours without completion. The script is run to migrate 5 million records.

UPDATE IS_FACT_RESPONSE_ROOT SET  IS_FACT_RESPONSE_ROOT.ROOT_ID = (
    SELECT CASE WHEN  PARENT_ID IS NULL THEN FACT_RESPONSE_ID  ELSE PARENT_ID END
    FROM  IS_FACT_RESPONSE 
    WHERE IS_FACT_RESPONSE_ROOT.ROOT_ID=IS_FACT_RESPONSE.FACT_RESPONSE_ID
) ;

The requirement is to remove the upgrade query from the script.
