Upgrade CMS From Any Lower Version To Latest

This tutorial explains how to upgrade your old CMS version, for example CMS 3.0, to the latest CMS 8.0 without losing your current games, users, blogs, settings, or website content.

The upgrade system uses a file called upgrade-database.php and a latest database structure file called database.sql. The script compares your old database with the latest CMS database structure and adds only the missing tables and columns.

✅ What This Upgrade Does

The upgrade tool checks your old database and repairs the missing structure needed by the latest CMS version.

• Creates missing tables

• Adds missing columns

• Keeps your existing games and users

• Keeps your blogs, settings, and content

• Reads only the table structure from database.sql

• Does not import demo games or overwrite your current data

⚠️ Before You Start

Always make a full backup before upgrading. Backup both your website files and your database. This is important because every website can have different custom changes.

Do not replace this file:

assets/includes/config.php

This file contains your current database login. Keep your old config file so the new CMS can connect to your existing database.
