Upgrading from MariaDB 11.4 to MariaDB 11.8

This page includes details for upgrading from MariaDB 11.4 to the subsequent long-term maintenance version, MariaDB 11.8.

How to Upgrade

For Windows, see Upgrading MariaDB on Windows.

• On SLES, OpenSUSE, and other similar Linux distributions, execute the following:sudo zypper remove MariaDB-server
