One-pass migration from Serato crate files 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 Serato DJ to Engine DJ normally means an XML round-trip: export from Serato DJ, hope Engine DJ parses it correctly, manually rebuild playlist groups, smart playlists, history sessions, 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: Engine DJ expects matching analysis files (.dat) next to each track for performance — pure path writes without analysis miss waveforms and cues.

Serato DJ and Engine DJ 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 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 Serato DJ'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 %% separator encodes nested crate folders and writes playlist groups, smart playlists, history sessions 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 Engine DJ receives a clean library.
Yes. Serato DJ 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 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 Engine DJ playlists, since Engine DJ has no direct equivalent.
Free tier covers detection and viewing. Lifetime access is $49 — $19 for the first 100 DJs.
