What happens to existing issue links if we introduce new hierarchy level in Advanced Roadmap?

[Deepanshu Natani]

A question related to Advanced Roadmaps:
What happens to existing links between issues if we introduce a new hierarchy level in between?
For example, suppose the current hierarchy configured is Initiatives -> Epics -> Story, 

Epics and Initiatives are linked using the Parent link.

Now, if we introduce a new hierarchy level "Feature" in between Initiatives and Epics, the hierarchy will be
Initiatives -> Features -> Epics -> Story.

Now, what happens to the existing links between Epics and Initiatives?

Hi @Deepanshu Natani - The links will remain.  It's not like making a workflow change where Jira performs an exhaustive review of all existing issues and adjusts accordingly.  Instead, it's a simple config change. From there you would go into all of your epics and relink them accordingly.
