We want to display the backlog hierache, we already have in TFS, in JIRA.
In TFS we have epics on the highest level. Epics are different projects to which we can assign different features. A feature is subdivided in product backlog items and the product backlog item is subdivided in tasks.
Epic --> Feature --> Product Backlog Item --> Task
How can we display this hierarchy in JIRA? There are one hierarchy level less in JIRA?
In the JIRA Backlog we can create different issue types (task, story, bug, epic) which are all on the same hierarchy level.
Furthermore we can create superordinate epics to which we can assign the single issue types. (It's a littel bit unusual to subordinate epics to an epic!?) It is also possible to create sub-tasks for every issue type.
Is it correct, that the epics in JIRA are similar to the features in TFS?

Many thanks in advance!
Best
