One-pass migration from Serato crate files 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 Serato DJ to Traktor normally means an XML round-trip: export from Serato DJ, hope Traktor parses it correctly, manually rebuild folder nodes inside the collection XML, discover cues didn't translate. Paths live in two places at once — the main Serato DB and every individual .crate file — so any reader that touches only one ends up half-broken. And on the destination side: Writes have to preserve every existing node (history, remix decks, samples) or Traktor refuses to load the collection.

Serato DJ and Traktor speak completely different languages: Serato crate files (Smart Crates are rule-based queries, not static lists — they have no direct equivalent in most other apps and need to be snapshotted at transfer time) 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 Serato 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 %% separator encodes nested crate folders and writes folder nodes inside the collection XML natively so the structure survives the migration.
Run Fix Missing Tracks for Serato DJ first. MLD scans your drives, matches moved/renamed files, and repairs links in Serato DJ before the transfer — so Traktor receives a clean library.
Yes. Serato DJ and Traktor libraries are both copied to timestamped backups before any write. Rollback is always one folder away.
Yes — see the Traktor to Serato DJ guide. MLD supports every direction between supported apps.
Smart Crates are rule-based queries, not static playlists. MLD snapshots them at transfer time to regular Traktor playlists, since Traktor has no direct equivalent.
Free tier covers detection and viewing. Lifetime access is $49 — $19 for the first 100 DJs.
