An upgrading guide for unmaintained versions of MariaDB Community Server.
This page includes details for upgrading from to . Note that and are both short-term releases, only maintained for one year.
For Windows, see Upgrading MariaDB on Windows.

On Debian, Ubuntu, and other similar Linux distributions, see for more information.
On RHEL, CentOS, Fedora, and other similar Linux distributions, see for more information.
On SLES, OpenSUSE, and other similar Linux distributions, see for more information.

Uninstall the old version of MariaDB.
On Debian, Ubuntu, and other similar Linux distributions, execute the following:sudo apt-get remove mariadb-server
On RHEL, CentOS, Fedora, and other similar Linux distributions, execute the following:sudo yum remove MariaDB-server
On SLES, OpenSUSE, and other similar Linux distributions, execute the following:sudo zypper remove MariaDB-server
