How to Convert a Rekordbox Library to Traktor or Serato Without Losing Cues and Grids

You have years of work in Rekordbox: hot cues on every drop, hand fixed grids on hard techno tracks that the analyser got wrong, and playlists for every type of set. Now you need Traktor for a new controller, or Serato for a residency where that is the house setup, and the thought of redoing it all is enough to make you stay put.

The good news is that you do not have to start from zero. The bad news is that no route is perfectly lossless. This guide covers what transfers, which tool to use for which direction, what OneLibrary changes in 2026, and the checks that stop a converted library from embarrassing you in a club.

Can Traktor or Serato import a Rekordbox library directly?

Not in a way you should rely on for a full library. You can drag playlists between apps or export M3U playlists, but that only moves the list of files, not the cue points or beatgrids. Serato reads its own cue and grid data from tags written into the audio files, and Traktor keeps its data in a collection file called collection.nml. Rekordbox keeps everything in its own database.

Because the three apps store performance data so differently, the reliable route goes through a converter that reads Rekordbox data and writes it in the other format. Almost every converter starts from the same place: the Rekordbox XML export.

Step 1: back up and clean up before you convert

Do this before anything else, because a converter that writes tags into files or overwrites matching tracks in a target library can do damage that is hard to undo.

• Back up your Rekordbox library using its own backup option, and copy your music folder to a separate drive.
• Back up the target app too. For Traktor that means a copy of collection.nml; for Serato, a copy of the _Serato_ folder.
• Relocate any missing files in Rekordbox first. A converter cannot carry cues for a track it cannot find.
• Delete playlists you no longer use. Converting a messy library just gives you a messy library in a new app.

Step 2: export your collection as XML

In Rekordbox, use the option to export your collection in XML format and save the file somewhere easy to find. This XML contains your tracks with their file paths, BPM, key, beatgrid markers, hot cues, memory cues, loops and playlist structure. It is a snapshot, so if you keep preparing tracks in Rekordbox afterwards, export a fresh one before each conversion.

Keep the file paths stable. If you move your music folder between exporting the XML and importing into the new app, the paths in the XML no longer match and tracks show up as missing.

Step 3: choose the right converter

Several tools do this job. They differ in price, platform and how much control you get.

• Lexicon: a library manager that can sync between Rekordbox, Traktor and Serato. It documents what happens on the Serato side clearly: Rekordbox playlists become crates, folder structure becomes subcrates, and memory cues are merged into the hot cue list.
• rekordcloud: a web based converter for Rekordbox, Traktor, Serato, VirtualDJ and Engine DJ on macOS and Windows. It carries track info, cues, grids and playlists, and warns about MP3 timing offsets with a separate scanner to correct them.
• Rekord Buddy: a long standing option for moving cues and grids between apps, popular with DJs who switch between platforms regularly.
• DJ Conversion Utility: a Mac only app that converts between Rekordbox, Traktor and Serato.
• Open source scripts: projects such as rb2serato on GitHub move Rekordbox data into Serato DJ Pro 4. They are free but expect you to be comfortable with the command line.

If you are converting once and staying on the new platform, a single paid conversion or trial is usually enough. If you will keep playing on two systems, for example Traktor at home and CDJs in clubs, a library manager that keeps both in sync is worth paying for.

What gets lost or changed in the move?

Every route has trade-offs. Know them before you test, so you can tell a tool problem from a format limit.

• Hot cue limits: Serato holds 8 hot cues per track. Rekordbox lets you add memory cues on top of hot cues, so some tools keep the first 8 and merge or drop the rest.
• Memory cues: Traktor and Serato do not treat them the way Rekordbox does, so they often arrive as extra hot cues or plain cue markers.
• Beatgrids: a single fixed grid usually converts well. Tracks where you built a variable grid for live drummers or tempo drifts are the most likely to need manual fixing.
• MP3 timing: different apps decode some MP3 files with a small offset at the start. That can shift every cue and grid line by a few milliseconds, enough to make a beat jump feel loose. Use a converter that corrects for this or test MP3s specifically.
• File formats: Lexicon notes that AAC files are not supported when syncing to Serato, so convert or replace those first.
• Colours, ratings, comments and smart playlists: these vary by tool and often do not carry across, so rebuild the ones you actually use.

Does OneLibrary make conversion unnecessary?

Possibly, for some DJs. In October 2025 AlphaTheta, Algoriddim and Native Instruments announced OneLibrary, a shared USB library format based on what Rekordbox previously called Device Library Plus. The aim is that a USB stick prepared in one app carries playlists, cue points, loops and beatgrids that the other apps and compatible players such as the CDJ-3000, CDJ-3000X and XDJ-AZ can read.

At launch, djay Pro and Rekordbox supported OneLibrary export, while Traktor support was announced for later updates. AlphaTheta's own guide says converting an existing Device Library to OneLibrary needs Rekordbox 7.2.11 or later. Before you bet a gig on it, check the release notes for your exact Traktor or djay version and test a stick on the same player model you will be using.

OneLibrary is about USB play. If you want to perform from a laptop in Traktor or Serato, you still need your data inside that app's own library, so a converter remains the practical route.

Traktor or Serato: which move is easier?

In practice, moving to Serato tends to be the simpler conversion for hot cues, because Serato's model of 8 hot cues per track is easy to map. The work is in deciding what happens to your memory cues and in making sure every file can carry Serato's tags. If you rely heavily on memory cues for mix in points, rename or recolour your most important hot cues before converting, so you know which ones survive.

Moving to Traktor puts more weight on grids. Traktor's beatgrid handling is strict and its sync is built around the grid, so a track whose grid is slightly off will drift during long blends. Hard techno and industrial tracks with distorted kicks are the usual offenders, because analysers struggle to find a clean transient. Plan extra time to re check grids on these tracks, and fix the source in Rekordbox first if you are keeping both apps.

Whichever way you go, keep your file organisation independent of the app. A clear folder structure on disk, consistent file names and proper tags make every future conversion easier, and they protect you if a database ever corrupts.

How to check a converted library before a gig

Do not play out on a converted library until you have spot checked it:

• Pick 20 tracks you know well, including your most edited hard techno tracks and a few MP3s.
• Check that the first downbeat sits on the grid and that the grid holds through the track.
• Trigger every hot cue and listen for anything that lands slightly early or late.
• Check that loops are the right length and that key values look sensible.
• Play a short practice mix using beat jumps and loops, the features that expose small offsets fastest.

What to do this week

• Back up both libraries and your music folder to a separate drive.
• Export a fresh Rekordbox XML and convert one playlist, not the whole library.
• Run the 20 track spot check, note which problems are format limits and which are tool issues.
• Only then convert the rest, and keep Rekordbox untouched until your first gig on the new setup goes well.
