Syncing myPHPadmin DBs

Hi

I have Kodi18 running through the house (platform is Linux (raspberryPi Libreelec but thats not important))

I use a MyPHP Admin DB to sync librarys across all devices. I want to use CinemVision now on a device connected to a projector. So my plan is to downgrade to Kodi17 but then the DB sync will be out of line between this device and the rest.

I was wondering if i could do a 2 way since on my PHPadmin to get over the issue of using 2 kodi versions

what do you guys think?
