MySQL 8.0 has reached its End of Life (EOL), which means it will no longer receive updates, security patches, or bug fixes. For organizations running MySQL in production environments, continuing to use an unsupported version can introduce security risks, compatibility challenges, and operational limitations. Because of this, upgrading to the MySQL 8.4 Long-Term Support (LTS) release has become an important step for maintaining stable and secure database systems.
In this course, we will walk through the complete upgrade journey from MySQL 8.0 to MySQL 8.4 LTS with practical demonstrations and real-world considerations. Instead of focusing only on theory, the course is designed to provide a hands-on learning experience so you can understand how upgrades work in real environments.
You will learn how to properly prepare your MySQL environment before performing an upgrade, identify compatibility issues that may impact applications, and use tools such as upgrade check utilities to validate your system. The course will also demonstrate multiple upgrade approaches, including in-place upgrades and replication-based upgrades, so you can choose the most suitable method for your environment.
In addition, we will discuss rollback strategies and important precautions to take before upgrading production systems. This course focuses on practical upgrade strategies and operational best practices, helping you perform MySQL upgrades safely, confidently, and with minimal risk in real-world environments.
Let’s get started and explore how to upgrade to MySQL 8.4 LTS.
