I am trying to add a new issue type (Feature) between Epic and Story. As per this post "https://jira.atlassian.com/browse/JSWCLOUD-18875" it seems to be possible.
Now when I am trying to:
1. Rename the Epic level to "Feature" and associate Feature issue type to it and I am able to change the name and associate "Feature" issue type to the hierarchy. However I am not able to disassociate existing Epic from it. -> so the Feature Hierarchy has two issue type "Epic" and "Feature" associated with it.
2. I tried to delete the existing issue type "Epic", but in the Epic description it is mentioned that -> "A big user story that needs to be broken down. Created by Jira Software - do not edit or delete"
Please help me achieve it.
