The Epic Link field is a calculated field (i.e. it's not real or stored in the database), it exists purely to allow JQL searches to search for issues linked to a parent issue. The actual link between an Epic and its stories is implemented using an issue link, not a field. There's no way to edit this link directly.
I've found that if you're in the backlog view and using JIRA Software, you can highlight issues and drag to "Issues without epics" under the "Epics" sidebar. This is limited to issues 'unresolved' though.
Hope that helps a little.
