One-pass migration from Traktor collection.nml into djay Pro JSON library. Playlists and collections preserved end-to-end, format gotchas handled on both sides, nothing leaves your machine.
Moving from Traktor to djay Pro normally means an XML round-trip: export from Traktor, hope djay Pro parses it correctly, manually rebuild playlists and collections, discover cues didn't translate. Traktor's NML schema mixes playlist data, history, and remix sets — parsers that don't understand the full schema lose data on round-trip. And on the destination side: Writes have to respect djay Pro's iCloud sync — direct edits to local files get overwritten on next sync.

Traktor and djay Pro speak completely different languages: Traktor collection.nml (Traktor stores stripe/waveform data per track in a separate analysis folder — moving tracks without the analysis files loses visual previews) versus djay Pro JSON library (djay Pro integrates tightly with Apple Music and Spotify streams alongside local files — tracks that came from a stream have no portable file path). XML export-import is the usual bridge — and it's lossy on both ends. MLD treats both formats as first-class, reads Traktor's structure natively, and writes djay Pro's native format directly, so playlists and collections 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 folder nodes inside the collection XML and writes playlists and collections natively so the structure survives the migration.
Run Fix Missing Tracks for Traktor first. MLD scans your drives, matches moved/renamed files, and repairs links in Traktor before the transfer — so djay Pro receives a clean library.
Yes. Traktor and djay Pro libraries are both copied to timestamped backups before any write. Rollback is always one folder away.
Yes — see the djay Pro to Traktor guide. MLD supports every direction between supported apps.
Traktor stripe/waveform data lives in a separate analysis folder. MLD moves those alongside the playlist transfer so visual previews survive in the target app where the format allows.
Free tier covers detection and viewing. Lifetime access is $49 — $19 for the first 100 DJs.
