TFS 2012 with SCRUM template have three different work items: PBI, Bug and task.
In Jira we have some more (including our own) - user story, epic, bug, task, technical sub-task, improvements, clarifications and a couple of more.
Now - all of these do not have to be synced to TFS - e.g. clarification.
I assume the sync for some issues is as follows:
User story > PBI
Bug > Bug
Technical sub-task > task
What do you usually do about the rest? 2013 can link Features with Epics I guess; but what about the other "developer-related" tasks that should be synced? How do I map them? Do I create similar work item types in TFS?
