Once a business has Jira Premium and has hierarchy beyond Epics (we want Story - Feature - Epic confusingly). Can there be applied selectively across the Jira instance (like a scheme is) or is it a one size fits all for the whole instance?
Also, when we transfer from Story - Epic to Story - Feature - Epic is Jira Premium able to keep the mappings that are there? We would want to swap all 'old epics' to be called features, then build 'new epics' above these.
