• renames the corp_processing table to corp_processing_old, preserving existing data
• creates empty corp_processing table same as before
• dumps rows from corp_processing from dump to empty newly created corp_processing in target table
• checks if (corp_num, flow_name, environment) has same already exists then handle it with updated data , inserts rows from corp_processing to corp_processing_old , now corp_processing_old has all the data
• deletes table temp corp_processing
• alters the name from corp_processing_old to corp_processing
