Неизвестный столбец cms_page.path при обновлении django-cms до 3.1

В настоящее время я пытаюсь обновить существующий сайт django-cms с 3.0.16 до 3.1.4 с помощью django 1.7.11

Я выполнил инструкции, данные в http://docs.django-cms.org/en/latest/upgrade/3.1.html, но когда я доберусь до python manage.py migrate

Я получаю следующую ошибку:

django.db.utils.OperationalError: (1054, "Unknown column 'cms_page.path' in 'field list'")

Любые подсказки о том, как я могу это отладить? Спасибо!

Вот полная трассировка:
