ESX to QBCore Migration Guide - QBCore Guide for FiveM

Introduction

This tutorial turns ESX to QBCore Migration Guide into a clean, developer-friendly guide for QBCore/FiveM. You will follow a step-by-step flow, copy the relevant code patterns, and learn the “why” behind the setup.

Requirements

• QBCore installed and running on a dev server
• Basic Lua knowledge and comfort reading FiveM patterns
• A test workflow for iterating safely (dev server, not production)
• Optional: a code editor with Lua/FiveM helpers (VS Code recommended)

Step-by-Step Guide

Step 1: Why teams migrate

In this step, you will apply the why teams migrate concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 2: Pre-migration checklist

In this step, you will apply the pre-migration checklist concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 3: Framework concept mapping

In this step, you will apply the framework concept mapping concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 4: Phase 1 – Prepare QBCore baseline

In this step, you will apply the phase 1 – prepare qbcore baseline concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 5: Phase 2 – Migrate player data

In this step, you will apply the phase 2 – migrate player data concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 6: 1. Create staging tables

In this step, you will apply the 1. create staging tables concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 7: 2. Transform ESX player rows

In this step, you will apply the 2. transform esx player rows concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 8: 3. Migrate owned items

In this step, you will apply the 3. migrate owned items concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Code Example

CREATE TABLE qbcore_players LIKE qbcore.players;
ALTER TABLE qbcore_players ADD COLUMN esx_identifier VARCHAR(60);

Tips & Best Practices

• Keep authority on the server: validate inputs before money/database operations.
• Start with one resource/module at a time, then refactor after you verify it works.
• Use callbacks for request/response flows and events for push/UX updates.
• When you run loops, avoid freezes: always yield with Wait() (client/server) and cache hot values.
