What are the issue types that are automatically added with Portfolio (Advanced Roadmaps)

[Jeremy Schrek]

I am going through an issue type clean up in our JIRA instance and we recently purchased Portfolio. I wanted to make sure I was not deleting any unused issue types (that have not tickets) that are required by Portfolio but I cannot find that in the documentation

@Jeremy Schrek - As long as you don't delete EPIC, Story, Task, and Subtask, then you should be safe.  In regards to Jira issue types, there are two major issue type categories: Standard and Subtask.  Portfolio provides the functionality of creating hierarchy aboves EPIC for rollup.

When you delete issue types in your env, you just need to pay attention on what existing issue types are being used by your users.

Best, Joseph

Is there any documentation on this? I know that many large plug-ins create ticket types that will cause issues if removed (X-Ray)
