Source migration ​

Migration is the process of moving series between sources without losing progress. This is most often used when a source is no longer accessible or another source is more up-to-date.

WARNING

Always make sure to have a backup in case anything unexpected occurs.

DANGER

Downloaded chapter(s) do not transfer with migrations.

Migrations with downloaded chapter(s) may leave the download behind. You will need to remove these manually with a file manager.

Migration guide ​

However you start it, migration runs the same three steps: pick where to search, look over what was found, then confirm. It works the same for manga and for light novels.

Starting a migration ​

From a whole source

Best when a source has died and you want everything off it.

  1. Go to Browse and open the Migrate tab.
  2. Pick the source to move away from. The list shows how many of your entries came from each one, and All / Manga / Novels filters it.
  3. Tap the entries you want, or use Select all in the toolbar.
  4. Tap Continue.

From one series

  1. Open the series.
  2. Open Overflow and tap Migrate.

From your library

  1. Long-press an entry in Library to start selecting.
  2. Tap the others you want.
  3. Open the overflow at the end of the bottom bar and tap Migrate.

Grouped entries ask which source to move first

If what you picked is a merged group, a Migrate screen lists its sources with their chapter counts so you can choose the one to move. Everything else is left where it is. Entries that are not grouped skip this step, as does the whole-source route above.

The Migrate screen lists your sources under Selected and Available. Only the selected ones are searched, and dragging reorders which is tried first.

  • Select all and Select none are in the toolbar, and Select pinned sources is in its overflow.
  • The sliders icon opens Search options.
Search options
  • Additional keywords (optional) narrows the search when a title alone finds too much.
  • Hide entries without a match and Hide entries without newer chapters trim the list you have to read.
  • Advanced search mode breaks the title into keywords for a wider search.
  • Match based on chapter number picks the match that is furthest ahead, rather than the first by source order.

The app warns you about the last two, and means it: both are slow and hit sources hard enough to get you rate-limited or blocked.

Tap Continue when you are happy.

Looking over the matches ​

One entry goes straight to a search screen: tap the result you want.

Several entries open the Migration list, which searches in the background and counts up as it goes. Each row names the entry, the move it found (current source → match), and how the chapter counts compare (Latest: 68 → 201), so you can see at a glance whether a match is worth taking.

Tap the double-check icon in the toolbar to accept every match at once, or use a row's overflow:

  • Search manually opens a search you drive yourself, for when the automatic match is wrong. Tapping a source's header there browses that one source with its own filters.
  • Migrate now moves that one entry, and Copy now adds the new source while leaving the old entry in place.
  • Don't migrate skips the row.

Backing out asks Stop migrating? first, so nothing is half-done by accident.

Confirming ​

Confirming asks which data to carry over. Tracking always carries; the rest is up to you, and there is an option to delete the old entry's downloads afterwards.
