Hi buger, Since the kind class has changed, the new validation logic is applied when loading older objects, as you noticed. I think the simplest way to get these objects and migrate your data would be to get them using the old class definition and assign values to the properties which will be required in the newer version. Another option would be to manually edit the problematic entities using the admin console's Data Viewer.
