Hello, I want to add an extra Feature level in the hierarchy between Initiative and Epic. I have no idea what the impact will be on existing Epics that already have a Parent Link with an Initiative. I have searched online and read plenty of related articles, but no clarity on this specific question yet.
I see this message: Changes to the hierarchy configuration will only apply to plans in Advanced Roadmaps 
Is this true? Some Epics in our instance have a Parent Link with an Initiative and I am worried these tickets will loose their link. Anyone that have experience with this hierarchy change?
