Server Version#: 1.21.3 Win 10
Player Version#: 4.51.1 for plex web (using browser)
I migrated/copied plex media center folders to duplicate Win 10 server on a QNAP. Somehow the music playlists on the source server all lost content but the video playlists did not. The playlists all show up on both the source and destination servers but they have no content. I followed steps to repair corrupted DB using SQLITE3 - no change. Only think I can think of is somehow the music folder lost contents during the copy process and had to rescan while the video folders did not. All media content is present and working fine although some album artwork has changed. I am not sure if all music metadata was lost or not yet. 2,000 albums. Thousands of songs on the music playlists - is there anything that can be done? (Not sure I have a recent backup. I was rebuilding the QNAP TS451 and needed my offsite drive for it. Never figured anything would happen to my source server metadata.
Moving a Plex server installation to a completely different computer architecture is not officially supported and will always come with some losses.
That article https://support.plex.tv/articles/201539237-backing-up-plex-media-server-data/ only covers moving between machines with identical architectures/operating systems.
The folder path looks differently on Linux than on Windows.
e.g. D:\Movies\My Awesome Movie (2021)\My Awesome Movie (2021) - 1080p.mkv
QNAP NAS’s run Linux.
e.g. /volumes/share1/Movies/My Awesome Movie (2021)/My Awesome Movie (2021) - 1080p.mkv
While Plex can use their unique universal “metadata ID” for movies, to reference them in playlists, for music it has to use the file path and filenames.
And since that file path has changed, your playlists are now pointing to music files which are no longer present under their previous folder locations.
That’s why your playlists still work for movies but not for music.
If you still have the old database copy, you can try to change all the old Windows folder paths to their Linux counterparts, as described in here.
This is strictly unsupported, though.
It figures. I did this once already weeks ago and it worked flawlessly. Everything came over. Followed Lon Syban’s video and everything worked perfectly for weeks. I saw the playlists automatically adapt to the new folders on the QNAP and everything. Unfortunately, I had to redo it because I inadvertently set the QNAP up for RAID0 instead of RAID5. Followed same steps to copy media & PMS Folder but must have missed something because now the playlists are empty on both the Win-10 source machine and the QNAP. (I’m, guessing something happened before the copy.) Stupid not backing up the PMS folder first. At least I understand why video is working and music isn’t.
One thing that does irritate me is that PlexAmp doesn’t work now either. I had the playlists downloaded to Android and Apple devices to play offline but now those are blank too. That’s not cool.
