Add a second Issue type to an existing hierarchy level

[Drew Watson]

In Settings-> Issues -> Issue Type Hierarchy

I currently have a hierarchy of:

- Programme

- Initiative

- Epics

- Story (and all other standard types)

- Sub Task

I want to add a second issue type at the same level at initiative:

- Programme

- Initiative, Milestone

- Epics

- Story (and all other standard types)

- Sub Task

I'm hoping I can use it (Milestone) on Advanced Roadmaps to show major milestones like Customer deadlines.

My concern is that when I try to add it to the hierarchy I get this message:

"Are you sure you want to change the hierarchy configuration?

Moving or changing hierarchy levels of issue types will break existing parent links in all company-managed projects in your site. This change can't be reversed."

I'm not inserting a new hierarchy level so I can't see an issue - but I also don't trust Jira not to just drop all the links between the Epics and Initiatives across the entire company...

Has anyone tried this?

Hi Drew, have you solved this issue? I'm having the same concern here...

Hi Nico - no.  Nothing even vaguely complex gets solved on these forums.  Usually just stuff you can figure out yourself given some time.

I have solved this since.  I just decided to press the button and it worked as hoped.
