unique_together modifed after data is loaded

Hi
 
Initially when we created the table we had two fields as unique_together = ( 'field1',field2') and quite some data has been added with the same

Later we added one more field to unique_together = ( 'field1',field2','field3')

how can I flush the old indexes created and add the new ones


Thanks
