Syncing Playlists Between Two Jellyfin Instances

[I-G-1-1]

if you open any jellyfin .xml file of a playlist you can find inside this for each track:

    <PlaylistItem>
      <Path>/path/to/your/audio/file/file.mp3</Path>
    </PlaylistItem>

So if you change the path your playlist become non-functional. 
At least you can easily find and replace the old path with the new path and recover the playlist.
