Hello Devs,
Currently there is no way to sync your watched status between different plex servers without using a plugin. If using these plugins they only provide the ability to sync at a user level (trakt.tv plugin) and not system level or are complicated to setup for people without coding knowledge. There is currently a way to download the database through the troubleshooting section of the settings.
When upgrading to a new server I had a look at the options for moving the database from the old to the new to sync mine and users I share the library with watched status of videos. I was only able to find ways of copying the database between server’s setup on the same operating system. When I moved from a QNAP NAS running plex to a new Server running TrueNAS Core I was unable to move the database.
My suggestion for a feature would be a way to download the old database from the old server which would include all of the watched/ not watched states of all videos on the server for all users (even the ones the library is shared with) and then upload them to the new one. This would of course need to be able to be done between different operating systems. If it could even be setup as a single button to for instance “Sync database to” and then you select the server which you wish to sync the database to. This would stream line upgrading servers and make it easier for not so tech savvy users to upgrade their plex server without losing watched state of videos.
