@natea I have not started working on this issue yet as I am on django oscar 2.0 right now. And you know , Total functionalities of django oscar are huge and you know all the django oscar and related apps were forked before to meet custom needs which have a complex upgradation path. Hope after the django oscar migration I will start working on dj-stripe upgrade.

As discussed I was having a duplicate index issue while trying to run migrate command. I found there are duplicate entries in the production db. For future reference just adding the two duplicated rows here.
