Don't import your exusting collection into Radarr or Sonarr for management. Just use them to manage new downloads. That might keep them from messing with your existing data.
1. Get Jellyfin up and running
2. Install qBittorrent and make sure it's downloads show up in Jellyfin
3. Install Prowlarr, and set up some indexers.
4. Install Sonarr and Radarr and link them to Prowlarr and qBittorrent.
- Verify they can find get torrents from Prowlarr and send then to qBittorrent.
- Verify they rename and copy files to desired folders once qBittorrent finished downloading.
5. Once all that is up and running, install Jellyseerr and connect it to Sonarr and Radarr and Jellyfin.
