Is there an option to edit linked issues in the next-gen backlog?

[Matan_Merling]

If I linked an issue and I want to change the relation of the linked issue, for example :

I want to change "Is cloned by" to "related to" how can I do it ? without deleting and creating the link all over again

The Greenhopper (now JIRA Agile) plugin would facilitate this on your boards, but alternatively you could restrict a search in issue navigator to epics and stories (or just not sub-tasks), and you should see the subtasks on the actual issue detail. Other than that, it's possible your previous employer had a standalone version of JIRA and a custom plugin that allowed for this as well.
