This is what zodbverify says when I do migration by the book (keeping Python 2 for now):
ImportError: No module named ZODBMountPoint.MountedObject: 1 ImportError: No module named SiteErrorLog.SiteErrorLog: 2 ImportError: No module named Product: 1
It seems to be caused by the temp_folder and error_log objects from Zope 2. The problem is that deleting the broken objects in Zope 4 and doing a pack does not remove those warnings. And temp_folder cannot be deleted in Zope 2. The warning about ZODBMountPoint.MountedObject stays whatever I do. Should I just ignore it?
