During a DV workbook migration to PROD (with Dataset 'DS' created from DB Table using DV connection 'DVCon') , even though 'Include Data' and 'Include Connection' is unchecked , this gets overwritten in Target instance.
The issue is that there is a separate Connection 'DVCon' with the exact same name with a different owner who did the import.
Upon trying to delete this DV Connection it says, 'Delete all the Dataset that use this connection first and try again'
There could be many datasets floating around unused and there is no way to track this or delete this unwanted DV connection .
