Using the Data Integration module I'm exporting redirects from the table UrlPath to a CSV - I can modify existing rows and import those back into DW. This works just fine.
But how would I add new rows? When I'm modifying rows, I can leave UrlPathID as it is - But what ID should I assign for new rows? If I leaving UrlPathID empty in the CSV and then run the import task - DW will return an error.
