We have completed the sprint 1 . It had a issue x which is also completed.
By client requirement we create sprint 2 and issue x enhancements come in sprint and name it as issue y. Can we keep the issue x in sprint1 as completed and work on issue y (which is enhancements of issue x of sprint 1). And keep it open in sprint 2. And keep sprint 1 completed with issue x as marked completed?
