As far as I can see the problem is the following change in ContentPanels.py
-class ContentPanels(BaseContent): + +class ContentPanels(base.ATCTContent): I have changed this code and now the migration steps works. Installing ContentPanels on a blank Plone hasn't got this problem, only the existing code during migration.
