Moving Plex server

So I am switching from freeNAS to unRAID and I am looking the best way to go about doing this without losing my watchlist. Does anyone have any suggestions?

Right now my plan is to

  • copy the metadata in my freenas jail
  • nuke the server after backing all my files up
  • install unraid and move media files back over
  • replace metadata file with the one I backed up with

would this work? I have my watchlist backed up but I have a couple other people I share my server with who I know dont have anything backed up.
