Here's what was done to migrate the root page on preprod.mykv.ch, just for documentations sake

```python

from wagtail.models import Locale, Page, Site
root = Page.objects.get(id=1)
mykv=Page.objects.get(slug='my-kv')
mykv.move(root, "first-child")

localhost=Site.objects.get(is_default_site=True)
localhost.root_page=mykv
localhost.save()

home=Page.objects.get(slug='home')
home.delete()

```

```bash
python manage.py migrate_translation --original kommunizieren-im-team --slug communicating-in-the-team --language en
python manage.py migrate_translation --original kommunizieren-im-team --slug communiquer-au-sein-de-léquipe --language fr
python manage.py migrate_translation --original zusammenarbeiten-im-team --slug collaborating-in-a-team --language en
python manage.py migrate_translation --original zusammenarbeiten-im-team --slug collaborer-dans-une-équipe --language fr
