Right now we are using JIRA onDemand and we already have set of Sprints in Classic Agile tab (GreenHooper). After most recent update we have new Scrum boards but if I create new board it doesn't contain Sprints from Classic Agile tab for the same project.
We have done a lot of work in Classic mode and we don't want to loose it. How can we migrate Sprints to new Scrum board?
