One-pass migration from Mixxx mixxxdb into djay Pro JSON library. Playlists and collections preserved end-to-end, format gotchas handled on both sides, nothing leaves your machine.
Moving from Mixxx to djay Pro normally means an XML round-trip: export from Mixxx, hope djay Pro parses it correctly, manually rebuild playlists and collections, discover cues didn't translate. Mixxx versions store the database in different locations on Mac, Windows, and Linux — auto-detection has to know all three. And on the destination side: Writes have to respect djay Pro's iCloud sync — direct edits to local files get overwritten on next sync.

Mixxx and djay Pro speak completely different languages: Mixxx mixxxdb (Mixxx is open source and free, so it's often the destination for DJs leaving paid apps — but the migration tooling around it is thin) 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 Mixxx'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 crates and folder-based browsing and writes playlists and collections natively so the structure survives the migration.
Run Fix Missing Tracks for Mixxx first. MLD scans your drives, matches moved/renamed files, and repairs links in Mixxx before the transfer — so djay Pro receives a clean library.
Yes. Mixxx 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 Mixxx guide. MLD supports every direction between supported apps.
Yes. MLD tracks Mixxx 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.
