We're using Visual Studio Online with Team Explorer in VS.Net 2013. When managing a work item, the iteration drop down contains a list of all iterations that have ever been defined without taking into consideration the Start and End dates. I would like this drop down to filter out iterations/sprints that have already been completed.
When I go into the management interface and ask to delete an old iteration, I get a message telling me that the work items that were attached to that iteration will need to be reassigned. I'd rather not do that - I want to maintain the historical link between a closed work item at the iteration under which it was delivered.
I'm wondering how others in my situation deal with iteration bloat, or if there is a setting that I'm not seeing.
