MySQL is a popular open-source relational database management system that is widely used for web-based applications and data management. MySQL 8.0 is the latest version of the software, but sometimes you may need to downgrade to an earlier version for compatibility reasons or to fix issues that may have arisen after upgrading.

Downgrading MySQL can be a bit tricky, but it’s not impossible. In this article, we will take a look at the steps you need to take to downgrade from MySQL 8.0 on Windows, Mac, and Linux.

Why Downgrade?

  • Bug fixes: If you have encountered bugs in MySQL 8.0 that are not yet fixed, downgrading to an earlier version may be the best solution.
  • Personal preference: Some users may simply prefer to use an earlier version of MySQL for personal reasons.
