Upgrading from MariaDB 11.2 to MariaDB 11.3

This page includes details for upgrading from MariaDB 11.2 to MariaDB 11.3. Note that MariaDB 11.2 is a short-term release, only maintained for one year. MariaDB 11.3 is a rolling release, after 11.3.2 one should upgrade to 11.4.2.

How to Upgrade

For Windows, see Upgrading MariaDB on Windows.

Before you upgrade, it would be best to take a backup of your database. This is always a good idea to do before an upgrade. We would recommend mariadb-backup.

The suggested upgrade procedure is:

1. Modify the repository configuration, so the system's package manager installs MariaDB 11.3. For example,

• On Debian, Ubuntu, and other similar Linux distributions, see Updating the MariaDB APT repository to a New Major Release for more information.

• On RHEL, CentOS, Fedora, and other similar Linux distributions, see Updating the MariaDB YUM repository to a New Major Release for more information.

• On SLES, OpenSUSE, and other similar Linux distributions, see Updating the MariaDB ZYpp repository to a New Major Release for more information.

1. Stop MariaDB.

2. 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

1. Install the new version of MariaDB.

• On Debian, Ubuntu, and other similar Linux distributions, see Installing MariaDB Packages with APT for more information.

• On RHEL, CentOS, Fedora, and other similar Linux distributions, see Installing MariaDB Packages with YUM for more information.

• On SLES, OpenSUSE, and other similar Linux distributions, see Installing MariaDB Packages with ZYpp for more information.

1. Make any desired changes to configuration options in option files, such as my.cnf. This includes removing any options that are no longer supported.

2. Start MariaDB.

3. Run mariadb-upgrade.

• mariadb-upgrade does two things:

  1. Ensures that the system tables in the mysql database are fully compatible with the new version.

  2. Does a very quick check of all tables and marks them as compatible with the new version of MariaDB .
