One-pass migration from Engine DJ m.db into Traktor collection.nml. Folder nodes inside the collection XML preserved end-to-end, format gotchas handled on both sides, nothing leaves your machine.
Moving from Engine DJ to Traktor normally means an XML round-trip: export from Engine DJ, hope Traktor parses it correctly, manually rebuild folder nodes inside the collection XML, discover cues didn't translate. Engine DJ versions 2.x and 3.x changed the schema — tools written for one version often miss data on the other. And on the destination side: Writes have to preserve every existing node (history, remix decks, samples) or Traktor refuses to load the collection.

Engine DJ and Traktor speak completely different languages: Engine DJ m.db (Engine DJ libraries live on the player USB/SSD itself as a per-drive Engine Library folder, not just on the home machine) versus Traktor collection.nml (Traktor stores stripe/waveform data per track in a separate analysis folder — moving tracks without the analysis files loses visual previews). XML export-import is the usual bridge — and it's lossy on both ends. MLD treats both formats as first-class, reads Engine DJ's structure natively, and writes Traktor's native format directly, so folder nodes inside the collection XML survives and the target app doesn't re-import anything. A timestamped backup of each app's library is taken before any write.
Yes. MLD reads both libraries locally, so both apps (or at least their library files) must be accessible on the same computer. Nothing uploads anywhere — all scanning is local.
Yes. MLD reads playlist groups, smart playlists, history sessions and writes folder nodes inside the collection XML natively so the structure survives the migration.
Run Fix Missing Tracks for Engine DJ first. MLD scans your drives, matches moved/renamed files, and repairs links in Engine DJ before the transfer — so Traktor receives a clean library.
Yes. Engine DJ and Traktor libraries are both copied to timestamped backups before any write. Rollback is always one folder away.
Yes — see the Traktor to Engine DJ guide. MLD supports every direction between supported apps.
Yes. MLD tracks Engine DJ version compatibility and updates with each new release. See the changelog for the version matrix.
Free tier covers detection and viewing. Lifetime access is $49 — $19 for the first 100 DJs.
