In Jira, how do I convert a story into an epic?

Solution 1:

You can do this through the More Actions dropdown:

  1. On the Story Page, select the "More Actions" dropdown
  2. then choose the "Move" option
  3. On the following dialog you'll be able to change the issue type to an epic

Solution 2:

Go to edit the story. From the edit page (popup in my case) you can change the story type to "Epic".
