MySQL Server Installations

MySQL Configurator adds an upgrade option if it finds an existing MySQL Server installation is discovered. It offers two options:


This upgrade functionality was added in MySQL 8.3.0.

In-Place Upgrade of an Existing MySQL Server Installation

This replaces the existing MySQL server installation as part of the upgrade process which may also upgrade the data schema. Upon success, the existing MySQL server installation is removed from the system.


The existing MySQL server instance must be running for the in-place upgrade option to function.

While MySQL Configurator may attempt (and succeed) to perform an in-place upgrade for other scenarios, the following table lists the scenarios officially supported by the configurator:

Table 1.2 Supported Upgrade Paths

A supported upgrade scenario Description
8.0.35+ to 8.1 From 8.0.35 or higher to the first MySQL 8 Innovation release.
8.0.35+ to 8.4 From 8.0.35 or higher to the MySQL next LTS release.
8.X to 8.Y where Y = X + 1 From an Innovation release to the next consecutive Innovation release.
8.3 to 8.4 From the last MySQL 8 Innovation release to the next MySQL 8 LTS release.
8.4.X to 8.4.Y where Y > X From within the same LTS release.
8.4.X to 9.0.0 From an LTS release to the first consecutive Innovation release.
8.4 to 9.7 From an LTS release to the next consecutive LTS release.

This dialogue prompts for the protocol (default: TCP/IP), port (default: 3306), and root password for the existing installation. Execute connect and then review and confirm the MySQL instance's information (such as version, paths, and configuration file) before proceeding with the upgrade.

This upgrade may replace the file paths. For example, "MySQL Server 8.2\Data\" changes to "MySQL Server 8.3\Data\" when upgrading 8.2 to 8.3.

This upgrade functionality also provides these additional options: "Backup Data" allows running mysqldump before performing the upgrade, and "Server File Permissions" to optionally customize file permissions.

Add a Separate MySQL Server Installation

Configure a standard side-by-side installation with the new MySQL server installation. This means having multiple MySQL server installations installed and running on the system.
