Is it possible to switch from osbuild generated ostree repos to bootc without touching the devices?

Hello.

My situation: We have some devices at customer location, in this Case Pi 4. Tese are using IoT images from ostree commits.

Is there a way to switch them to bootc without loosing configs or having to get the SD-Card in my hands?

Or is there even a way to convert generated Containers to ostree repositories so that I technically only have to deal with one image which can be used by already enrolled devices?

Kind regards,
Dirk
