Move from Radarr, Sonarr, Prowlarr, SABnzbd and other apps

Already running Radarr, Sonarr, Prowlarr, SABnzbd or NZBGet (on a Synology NAS or anywhere else)? Mediarium can copy your setup over so you don't have to type it all again. It moves no files. Your movies and shows stay where they are. The page is Settings > System > Move from other apps, and only administrators can open it. You can also bring over Jackett, NZBHydra2, Overseerr/Jellyseerr, Ombi, Bazarr, Medusa and SickChill (see the tables below).

It's read-only on the other side. Every request Mediarium sends to the other apps is a plain GET, except for NZBGet, which only speaks JSON-RPC over POST. There Mediarium calls just the read-only methods version and config. Nothing in those apps is changed, so you can try Mediarium next to them and switch over when you're ready.

What is brought over

Not brought over: download history, the blocklist, custom formats and release profiles, tags, import lists, notifications, Prowlarr's app links, SABnzbd's categories and scripts, episode-by-episode monitoring (seasons are kept), and which specials were monitored (Mediarium lists every special from TMDB; tick the ones you want, see Library).

No search is started for anything imported. Monitored titles with no file yet are picked up by Mediarium's regular automatic search, like any other wanted title (see Running both side by side to avoid downloading things twice), or you can search them yourself.

Running it again is safe. An import never adds something twice: movies and shows are matched by TMDB id, indexers by address (or site), and Usenet servers by host and username. Running it again only adds what's new, and links files that weren't found the first time (after you fix the folder mapping, for example).

Before you start

• Mediarium is installed and you've finished the first-run wizard, with your movies and TV folders set (Settings → Library → Folders). On a Synology, follow the Synology guide first.
• A TMDB API key is set (Settings → Info, lists and subtitles → Movie and show info), unless your copy of Mediarium came with one.
• The movies and TV folders Radarr and Sonarr use are mounted into Mediarium's container too (see Step 3).
• An address that goes through Cloudflare (a Cloudflare Tunnel, for example) can answer with an error like 530 when Cloudflare can't reach the app behind it. Use the app's address on your own network instead. Mediarium says so when it sees this.
• Mediarium can reach the other apps over the network. When they all run on the same NAS, use the NAS's address (for example http://192.168.1.20:7878), not localhost. Inside a container, localhost is the container itself.

Step 1: Find the addresses and API keys

You need each app's address and its API key, for the apps you want to import from. An app you fill in needs a full http:// or https:// address and its key (NZBGet needs a username instead), and the folder boxes in step 3 must be full paths. Mistakes are pointed out under the box before anything is checked.

If you gave an app a URL base (for example /radarr), include it: http://192.168.1.20:7878/radarr. The quickest way to get the right address is to open the app in your browser and copy what the address bar shows, up to the port (and URL base).

Step 2: Preview

Under 1. Connect your current apps, fill in the address and key of each app you use (leave the others empty) and press Check and preview. Mediarium reads the apps and shows, for each one:

• whether it could connect, and the app's version;
• how many items are to add, already here and skipped;
• every movie, show, indexer, server and request with what would happen to it and why (press Show all or Show the list on its card).

A preview changes nothing, in Mediarium or in the other apps. Common reasons you may see:

Step 3: Check the folder mapping

Radarr and Sonarr report where each title lives as their own container sees it, which may not be where Mediarium's container sees the same folder. After the preview, 2. Check your folders lists the root folders of Radarr, Sonarr, Medusa and SickChill, the same folder in Mediarium, and how many title folders were found there. Change the folder in the middle column if it's wrong, then press Check again with these folders.

A mapping says "what Radarr calls from, Mediarium calls to". Only the start of the path is swapped: with /movies → /data/media/movies, Radarr's /movies/Heat (1995) becomes /data/media/movies/Heat (1995).

Example: a Synology with a data shared folder.

/volume1/data
├── usenet/            SABnzbd's downloads
└── media/
    ├── movies/        your movies
    └── tv/            your shows

• If Radarr, Sonarr and Mediarium all map /volume1/data as /data (the layout the Synology guide uses), they see the same paths (/data/media/movies/...) and no mapping is needed.
• If Radarr maps /volume1/data/media/movies as /movies and Sonarr maps /volume1/data/media/tv as /tv, while Mediarium maps /volume1/data as /data, you need:

Suggestions. For a root folder that doesn't exist in Mediarium as it is, Mediarium suggests a mapping to its own movies (or TV) folder when the last folder names match (/movies and /data/media/movies both end in movies), or when Mediarium's folder holds the same title folders. A suggestion is used unless you enter your own mapping for that root folder, and the preview shows which ones are suggested. Check them: every root folder should show a green badge such as "12 of 12 title folders". A red badge means the folder wasn't found or holds no title folder.

Step 4: Import

Under 3. What will be imported, each app has a card with a tick box. Untick the parts you don't want (a Bazarr card starts unticked). Radarr and Sonarr profiles are listed under Quality profiles. Pick the Mediarium profile each one should become, or Default profile. Then, under 4. Import, press Import now. It runs in the background and shows its progress, and you can leave the page. At the end you get counts for each part (added, already here, skipped, failed) and the notes and errors, if any.

Running both side by side

You can keep the old apps running while you get used to Mediarium.

• Avoid downloading things twice. Radarr/Sonarr and Mediarium would both search for monitored titles that have no file. Until you switch, either turn off Automatic searching and downloading in Mediarium (Settings → Library → Quality → Automation; the Import step has the same switch, Pause automatic searching while I test), or unmonitor those titles in one of the two apps.
• Files downloaded by Radarr or Sonarr after the import aren't known to Mediarium yet. Run the import again (it only adds what's new), or use Import existing on the Library page (Import your library).
• Mediarium downloads with its own built-in Usenet and torrent downloaders into its own downloads folder, not through SABnzbd. Both use connections from your Usenet provider's limit, so if downloads fail with "too many connections", lower the connections in one of them.

Stopping the old apps

When Mediarium does everything you need, run the import once more to pick up anything new, then stop Radarr, Sonarr, Prowlarr and SABnzbd. On a Synology: Container Manager → Container, select them, Action → Stop (or stop their project). Keep them stopped, not deleted, for a few weeks in case you want to look something up. See If you already run other apps. None of this touches your movies and TV folders.

Troubleshooting

• "could not reach 192.168.1.20:7878": the address or port is wrong, the app isn't running, or a firewall is blocking it. Open the same address in your browser from another computer on the network.
• "the API key was not accepted": copy the key again from the place in Step 1. For SABnzbd, use the API Key, not the NZB Key.
• "this address is Sonarr, not Radarr": the addresses are swapped.
• "answered 404": check the URL base (the part after the port, if you set one in the app).
• Many titles "folder not found": the folder mapping is wrong, or the folder isn't mounted into Mediarium's container. The root folder list in the preview shows where each root folder ends up.
• Episodes left out ("aren't listed on TMDB for this show"): TMDB and TheTVDB sometimes number seasons differently (common with anime and long-running shows). Those files stay on disk, and Mediarium doesn't track them.

API

All three endpoints are for administrators. See API routes for the full route list.

• POST /api/migrate/preview with {radarr?, sonarr?, prowlarr?, sabnzbd?, nzbget?, jackett?, nzbhydra?, overseerr?, ombi?, bazarr?, medusa?, sickchill?, pathMap?, profileMapping?} (each app {url, apiKey}, except nzbget: {url, username, password}, jackett: {url, apiKey, direct?: ["<indexer id>", ...]} and nzbhydra: {url, apiKey, torznab?: true}; pathMap [{from, to}], profileMapping {"<Radarr/Sonarr profile name>": <Mediarium profile id>}) answers what an import would do, per app, changing nothing. API keys and passwords are never sent back.
• POST /api/migrate/run with the same body plus include ({movies, series, indexers, usenetServers, qualityProfiles, requests, subtitleLanguages}, each true unless set to false, except subtitleLanguages, which is false unless set to true) starts the import in the background (202), or answers 409 while one is running.
• GET /api/migrate/status follows it: {running, step, done, total, startedAt, finishedAt, results, items, errors, notes}.
• The preview has one key per app that was sent: radarr, sonarr, medusa and sickchill are {ok, error?, version?, summary, rootFolders, profiles, items} (Medusa and SickChill have no profiles); prowlarr, jackett and nzbhydra are {ok, error?, version?, summary, items} with indexers; sabnzbd and nzbget are {ok, error?, version?, summary, items, completeDir?, categories?} with Usenet servers; overseerr and ombi are {ok, error?, version?, summary, items} with requests (title, year, mediaType, tmdbId, tvdbId, status, requestedBy, seasons, action, reason); bazarr is {ok, error?, version?, included, summary, languages, current, new, providers, providersError?}. Every item has an action (add, exists or skip) and a reason.
• The status results has movies, series (Sonarr, Medusa and SickChill), indexers (Prowlarr, Jackett, NZBHydra2), usenetServers (SABnzbd, NZBGet), requests and subtitleLanguages, each {added, existing, skipped, failed, filesLinked, disabled}. The step goes through reading, movies, series, indexers, usenetServers, requests, subtitleLanguages and done, and each item's kind is movie, series, indexer, usenetServer, request or subtitleLanguages.
