MySQL Upgrade

(Home >> Software >> MySQL Upgrade)

Overview

This interface allows you to manage MySQL version upgrades (e.g., upgrading MySQL 4.0 to 4.1 or MySQL 4.1 to 5.1). Once you have selected your MySQL version, cPanel will automatically keep your MySQL installation up-to-date. This means that when a new patch is released for your version of MySQL, cPanel will automatically apply the patch to your installation.

Note: This feature does not support downgrading MySQL versions. Downgrades are not recommended.

Possible PHPMyAdmin Version Incompatibility

cPanel 11.25 added support for PHPMyAdmin 3. When upgrading to MySQL 5.0 and higher, PHPMyAdmin 3 is automatically installed. cPanel uses its own PHP binary (in /usr/local/cpanel/3rdparty/bin) to serve internal PHP applications, such as PHPMyAdmin. This is important because PHPMyAdmin 3 is not compatible with PHP 4. If you have not changed cPanel's internal PHP, you will not experience any problems with your MySQL upgrade. However, if you have overwritten cPanel's internal PHP binary (found in /usr/local/cpanel/3rdparty/bin) with PHP 4, upgrading to MySQL 5.0 or higher will result in a broken PHPMyAdmin installation.
