What you need before you start

Gather everything the old tracker holds before you leave it. Save the ratings, the watch dates and the list names into one file you can open later, such as a spreadsheet or a plain text file. Note which titles are movies and which are shows, because the two are handled separately.

If you plan to use Watcharr, the titles need to sit on a public IMDb list, since Watcharr reads those. ^[1] Watcharr also gives movies and shows separately, so split your list the same way before you start. ^[1]

Keep the old export until the new list is complete. Pick a short set of titles you care about most, so you can check them by eye after the first import.

Step by step

Export or copy your old ratings and watch history from the cloud tracker into a single file. Where the tracker offers a download, use it. Where it does not, copy the titles into one place by hand.
Put the titles you want to move onto a public IMDb list, and make sure the list is public before you continue. ^[1]
Keep movies and shows apart, because Watcharr gives one link for Radarr with the movies and one for Sonarr with the shows. ^[1]
Paste the IMDb list into Watcharr to get the two links. The links are built from the list's id, so the same list always gives the same links. ^[1]
In Radarr and Sonarr, click the bookmark that Watcharr offers for each app. The bookmark adds the list for you, using that app's API key without sending it anywhere else. ^[1]
Wait for the next check. Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[1]
Look for shows that were left out. Watcharr looks up TheTVDB ids through TVMaze and TMDB, skips the shows it cannot match, and tells you which ones it skipped. ^[1]
If you sign in, Watcharr re-reads the list about every 15 minutes and warns you when a list fails three reads in a row. ^[1]
Compare the new list with your old file. Delete the old file only when the two match where you expected.

Tools that can do it

Watcharr is made by the team that publishes this site, VLClean.

Watcharr turns a public IMDb list into links for Radarr and Sonarr, and each link acts like a small server that the app checks on a schedule. ^[1] The hosted version needs nothing to install and no account. ^[1] The page shows the list's covers in a row, and each cover opens TMDB's plot, genres, rating, backdrop and trailer. ^[1]

Signed-in users can combine several IMDb lists into one link per app for the whole household, and a title that is on two lists is added only once. ^[1] If a read of the list fails, the links keep serving the last list that loaded correctly. ^[1]

Its code can be read under the PolyForm Noncommercial 1.0.0 licence, and older versions remain under MIT. ^[1] Commercial use is not licensed, and no commercial licence is for sale. ^[1]

Other tools are not covered by the facts on this page, so this page says nothing about how they compare. Before choosing one, check whether it can read your exported history and ratings, how it passes titles to Radarr and Sonarr, and what it costs.

Common mistakes to avoid

Avoid pasting a list before checking that it is public. Watcharr reads public IMDb lists. ^[1]

Avoid expecting every show to arrive. Shows that Watcharr cannot match to a TheTVDB id are left out, and Watcharr tells you which ones were skipped. ^[1]

Avoid expecting changes to appear at once. Radarr checks the link every 15 minutes and Sonarr every 5, so a new title can take a while to show up. ^[1]

Avoid mixing movies and shows in one list. Watcharr gives each its own link, so keep them separate from the start. ^[1]

Avoid deleting the old export too early. Keep it until the new list has been checked against it.
