I'm getting ready to migrate an acquired company's Jira and Confluence into the acquirer's instance.
The source instance has Advanced Roadmaps installed but the destination instance does not.
In the source instance a custom initiative issue type was created and the hierarchy level was set above Epic in the AR add-on.
Does anyone know if/how this will migrate to the destination account without the AR add-on? Is there anything I can do to ensure the structure is retained?
