Just wanted to say I did an upgrade on Unraid, followed the directions and everything went well. I’m pretty familiar with advanced networking, etc. but having a Compose builder is pretty slick for newer users.
I had a few issues with some tracks being rescanned as if they were just added and I had to “replace” them in some playlists, but it took about 20 mins with the playlist analyzer tool. Any software migration you get away with only 20 mins of clean up on is a success in my book 
Great work to the team on this one.
