We're attempting to migrate our next-gen project to the classic project since it now has roadmaps enabled.
We performed a test migrations of a single epic, and three of it's child issues - everything went along nicely, all four issues were migrated successfully, parent links were maintained, including development tasks per issue.
However, we cannot see the epic in the classic Roadmap.
When we create new Epics, they will appear in the Roadmap - any migrated Epics don't seem to show up on the Roadmap. We want to maintain the development tasks against the epics and issues, so we prefer not to create new epics then assign the child issues to the new epic.
Any advice?
