One-pass migration from Engine DJ m.db into Serato crate files. %% separator encodes nested crate folders preserved end-to-end, format gotchas handled on both sides, nothing leaves your machine.
Moving from Engine DJ to Serato DJ normally means an XML round-trip: export from Engine DJ, hope Serato DJ parses it correctly, manually rebuild %% separator encodes nested crate folders, discover cues didn't translate. Engine DJ versions 2.x and 3.x changed the schema — tools written for one version often miss data on the other. And on the destination side: Every write must update both the main DB and each affected .crate atomically, or Serato shows ghost entries.

Engine DJ and Serato DJ speak completely different languages: 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) versus 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). XML export-import is the usual bridge — and it's lossy on both ends. MLD treats both formats as first-class, reads Engine DJ's structure natively, and writes Serato DJ's native format directly, so %% separator encodes nested crate folders 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 playlist groups, smart playlists, history sessions and writes %% separator encodes nested crate folders natively so the structure survives the migration.
Run Fix Missing Tracks for Engine DJ first. MLD scans your drives, matches moved/renamed files, and repairs links in Engine DJ before the transfer — so Serato DJ receives a clean library.
Yes. Engine DJ and Serato DJ libraries are both copied to timestamped backups before any write. Rollback is always one folder away.
Yes — see the Serato DJ to Engine DJ guide. MLD supports every direction between supported apps.
Yes. MLD tracks Engine DJ 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.
