If we have a jira in our sprint which is estimated at a 5. By the end of the sprint only 2 points of effort have been done on it.
We don't lose that effort. But there appears to be no way capture that. You either pull out of the sprint into the back log and pull into the new sprint and re point.
Or clone the Jira, add the 2 points in to the cloned Jira and put into Done, then pull the original into the backlog and pull into the new sprint and change to a 3.
