Meanwhile, a significant warning has been issued by Percona, a renowned MySQL expert, regarding the upgrade to MySQL 8.0.37 and beyond. Notably, this warning has sent shockwaves through the MySQL community, and for good reason. Initially, the warning was made public via an official Percona blog post, in which they expressed their concerns about the potential risks and complications associated with this particular upgrade. Consequently, many MySQL users are now left wondering whether they should proceed with the upgrade or wait until further notice. In the meantime, it is essential to understand the reasoning behind this caution and what it means for MySQL users.
Subsequently, it is crucial to examine the changes introduced in MySQL 8.0.37 that have led to this warning. Firstly, the new release includes several significant modifications to the MySQL optimizer, which could potentially lead to performance issues and unexpected behavior. Furthermore, the upgrade also includes changes to the MySQL query cache, which may cause problems for certain applications. Additionally, Percona has highlighted several other concerns, including the potential for data corruption and compatibility issues with certain plugins and extensions. As a result, it is vital to carefully evaluate the pros and cons of upgrading to MySQL 8.0.37 and beyond.
Understanding the Risks
In light of these concerns, it is essential to understand the risks associated with the upgrade.

Furthermore, they should also test the upgrade in a non-production environment to identify any potential issues and ensure that their applications are compatible with the new release. Additionally, users can also consider using tools such as MySQL Upgrade to simplify the upgrade process and minimize the risks. Meanwhile, they should also monitor the MySQL community and official documentation for any updates and guidance on the upgrade process.
Meanwhile, it is also essential to consider the potential benefits of the upgrade. Notably, MySQL 8.0.37 includes several significant improvements and new features, such as enhanced performance and security. Furthermore, the upgrade also includes several bug fixes and improvements to the MySQL optimizer, which could lead to better query performance and overall user experience. Consequently, users should carefully weigh the pros and cons of the upgrade and consider their specific needs and requirements before making a decision.
Here is an example of how to create a backup of a MySQL database:
mysqldump -u [username] -p[password] [database_name] > backup.sql
In the meantime, users can also take several steps to prepare for the upgrade. Firstly, they should review the official MySQL Upgrade Documentation to understand the process and any specific requirements. Furthermore, they should also test their applications and plugins to ensure compatibility with the new release.
