Hi,

I have used Kodi since the XBMC days and the Backup add-on for a long time as well and both work very well.

I am migrating away from all Microsoft products to Linux. How do I move the watched list from the Windows version to Linux please? I have tried making a backup and restoring that in Linux but the watched list doesn't seem to work. Is this possible and if so how please

I did the same thing about a year ago. Never looked back.

The watched status of movies and TV is stored in Kodi's internal database. When moving to Linux you will have to start from scratch in creating a new database and adding all your video sources. 

Before you migrate from Windows, you need to export the watched status that is contained in the internal database to the individual NFO files alongside all your video files. 

Go to Settings > Media > Library and select Export Library. Then Separate Files, then NO to export thumbnails, (your media folders usually contain thumbnail files already, you can select YES if you want to export them and store them in all the folders if you have the space.) Then Overwrite Old Files. This will refresh all your NFO files in your library with your current watched status.  

Now when you move over to Linux And you add your video sources in Kodi there, when it scans your sources it will automatically pick up your watched status from the NFOs in your library. Coincidentally I just completed this myself a few minutes ago when i moved to an SQL database on my server. It worked perfectly.
