Question running Kodi17 and Kodi18 on devices

Hi

I thought i would post here as the platform doesnt matter, its a question on running difference version of koid with a synced/shared library

I want to start using CinemaVision on one of my Pi’s. It’s only supported and working on Kodi 17. All my Pi’s are running kodi 18 libreelec 307.

Does anyone know what issues I might have rolling back one pi to kodi 17 while the rest progress with the libreelec beta builds?

Thinking about it, i dont think this will work at all….

Kodi 18 = Movie DB 108
Kodi 17 = Movie DB 107

So if i ran 4 kodi 18s and 1 kodi 17, i would have a split DB with different watched statuses wouldn’t I?

Thanks
Nick
