We are looking for a way to defer or move subtasks from an Issue into the backlog or defer them to the next sprint when it becomes clear that those subtasks will be done next sprint instead of the current sprint. Ideally, we could "keep them" for a future sprint without having to rewrite them as part of another story, then modify the story points to accommodate the reduced objectives and complete the modified user story with the reduced points being recorded and allocated to the current sprint.
Setting the status of the subtask to Backlog or Deferred does appear to allow one to close the story, but does not appear to allocate the points earned for the remaining Done subtasks. This is not what we expected.
Have we set up our "workflow" incorrectly or something? Are there other ways to accomplish what we're after? Of course we can make a new issue in the backlog and copy the text from each deferred subtask into it, but it seems like there ought to be a better way.
Note that I do also understand that one is supposed to scope the issue such that it CAN be completed within the sprint. But sometimes things change for us and we want to reduce the scope of an issue by splitting it.
