Best practise question: how do you associate teams in large projects?

[Martin Schwaiger]

Example: I have so set up a plan für several year, 12 main epics wigh a total of 280 stories underneath. Not all the programmers are totally interchangeable so not everybody can pick any task from any epic.

Would you create multiple teams and associate them to the epics (issue source)? In case one team finishes ealrlier with the tasks in this epic, would they be assigned to any other issue (inside the plan but outside the original issue source) by the autoscheduler or would they have some free time?
