One-pass migration from Mixxx mixxxdb into Engine DJ m.db. Playlist groups, smart playlists, history sessions preserved end-to-end, format gotchas handled on both sides, nothing leaves your machine.
Moving from Mixxx to Engine DJ normally means an XML round-trip: export from Mixxx, hope Engine DJ parses it correctly, manually rebuild playlist groups, smart playlists, history sessions, 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: Engine DJ expects matching analysis files (.dat) next to each track for performance — pure path writes without analysis miss waveforms and cues.

Mixxx and Engine DJ 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 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). 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 Engine DJ's native format directly, so playlist groups, smart playlists, history sessions 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 playlist groups, smart playlists, history sessions 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 Engine DJ receives a clean library.
Yes. Mixxx and Engine DJ libraries are both copied to timestamped backups before any write. Rollback is always one folder away.
Yes — see the Engine DJ 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.
