Note that [MariaDB 11.3](/docs/release-notes/community-server/old-releases/11.3/what-is-mariadb-113.md) is a [rolling release](https://mariadb.org/about/#maintenance-policy), and MariaDB 11.4 is a [long-term maintenance release](https://mariadb.org/about/#maintenance-policy). After MariaDB 11.4.2, one can continue to the next rolling release, 11.5.2, 11.6.2 and so on, or remain on the long-term series, [MariaDB 11.4.3](/docs/release-notes/community-server/11.4/11.4.3.md). MariaDB 11.4.4 etc. ### How to Upgrade For Windows, see [Upgrading MariaDB on Windows](/docs/server/server-management/install-and-upgrade-mariadb/upgrading/platform-specific-upgrade-guides/upgrading-mariadb-on-windows.md). For MariaDB Galera Cluster, see [Upgrading from MariaDB 10.6 to MariaDB 10.11 with Galera Cluster](/docs/galera-cluster/galera-management/upgrading-galera-cluster/upgrading-from-mariadb-10-6-to-mariadb-10-11-with-galeracluster.md) instead. 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](/docs/server/server-usage/backup-and-restore/mariadb-backup.md). The suggested upgrade procedure is: 1. Modify the repository configuration, so the system's package manager installs MariaDB 11.4. 1. On Debian, Ubuntu, and other similar Linux distributions, see [Updating the MariaDB APT repository to a New Major Release](/docs/server/server-management/install-and-upgrade-mariadb/installing-mariadb/binary-packages/installing-mariadb-deb-files.md#updating-the-mariadb-apt-repository-to-a-new-major-release) for more information. 2. On RHEL, CentOS, Fedora, and other similar Linux distributions, see [Updating the MariaDB YUM repository to a New Major Release](/docs/server/server-management/install-and-upgrade-mariadb/installing-mariadb/binary-packages/rpm/yum.md#updating-the-mariadb-yum-repository-to-a-new-major-release) for more information. 3. On SLES, OpenSUSE, and other similar Linux distributions, see [Updating the MariaDB ZYpp repository to a New Major Release](/docs/server/server-management/install-and-upgrade-mariadb/installing-mariadb/binary-packages/rpm/installing-mariadb-with-zypper.md#updating-the-mariadb-zypp-repository-to-a-new-major-release) for more information. 2. [Stop MariaDB](/docs/server/server-management/starting-and-stopping-mariadb/starting-and-stopping-mariadb-automatically.md). 3. Uninstall the old version of MariaDB. 1. On Debian, Ubuntu, and other similar Linux distributions, execute the following: `sudo apt-get remove mariadb-server` 2. On RHEL, CentOS, Fedora, and other similar Linux distributions, execute the following: `sudo yum remove MariaDB-server` 3. On SLES, OpenSUSE, and other similar Linux distributions, execute the following: `sudo zypper remove MariaDB-server` 4. Install the new version of MariaDB. 1. On Debian, Ubuntu, and other similar Linux distributions, see [Installing MariaDB Packages with APT](/docs/server/server-management/install-and-upgrade-mariadb/installing-mariadb/binary-packages/installing-mariadb-deb-files.md#installing-mariadb-packages-with-apt) for more information. 2. On RHEL, CentOS, Fedora, and other similar Linux distributions, see [Installing MariaDB Packages with YUM](/docs/server/server-management/install-and-upgrade-mariadb/installing-mariadb/binary-packages/rpm/yum.md#installing-mariadb-packages-with-yum) for more information. 3. On SLES, OpenSUSE, and other similar Linux distributions, see [Installing MariaDB Packages with ZYpp](/docs/server/server-management/install-and-upgrade-mariadb/installing-mariadb/binary-packages/rpm/installing-mariadb-with-zypper.md#installing-mariadb-packages-with-zypp) for more information. 5. Make any desired changes to configuration options in [option files](/docs/server/server-management/install-and-upgrade-mariadb/configuring-mariadb/configuring-mariadb-with-option-files.md), such as `my.cnf`. This includes removing any options that are no longer supported. 6. [Start MariaDB](/docs/server/server-management/starting-and-stopping-mariadb/starting-and-stopping-mariadb-automatically.md). 7. Run [mariadb-upgrade](/docs/server/clients-and-utilities/deployment-tools/mariadb-upgrade.md), to: 1. Ensure that the system tables in the [mysql](/docs/server/reference/system-tables/the-mysql-database-tables.md) database are fully compatible with the new version. 2. Perform a very quick check of all tables and marks them as compatible with the new version of MariaDB. ### Incompatible Changes Between 11.3 and 11.4 #### Options That Have Been Removed The following options should be removed if you use them in your [option files](/docs/server/server-management/install-and-upgrade-mariadb/configuring-mariadb/configuring-mariadb-with-option-files.md): | Option | Reason | | ------------------------------------------------------------------------------------------------------------------------------- | ------------ | | [debug\_no\_thread\_alarm](/docs/server/server-management/variables-and-modes/server-system-variables.md#debug_no_thread_alarm) | Unused code. | ### See Also * [Features in MariaDB 11.4](/docs/release-notes/community-server/11.4/what-is-mariadb-114.md) * [Features in MariaDB 11.3](/docs/release-notes/community-server/old-releases/11.3/what-is-mariadb-113.md) * [Upgrading from MariaDB 11.2 to MariaDB 11.3](/docs/server/server-management/install-and-upgrade-mariadb/upgrading/mariadb-community-server-upgrade-paths/upgrading-to-unmaintained-mariadb-releases/upgrading-from-mariadb-11-2-to-mariadb-11-3.md) * [Upgrading from MariaDB 11.1 to MariaDB 11.2](/docs/server/server-management/install-and-upgrade-mariadb/upgrading/mariadb-community-server-upgrade-paths/upgrading-to-unmaintained-mariadb-releases/upgrading-from-mariadb-11-1-to-mariadb-11-2.md) * [Upgrading from MariaDB 10.11 to MariaDB 11.4](/docs/server/server-management/install-and-upgrade-mariadb/upgrading/mariadb-community-server-upgrade-paths/upgrading-from-mariadb-10-11-to-mariadb-11-4.md) * [Upgrading from MariaDB 10.6 to MariaDB 10.11 with Galera Cluster](/docs/galera-cluster/galera-management/upgrading-galera-cluster/upgrading-from-mariadb-10-6-to-mariadb-10-11-with-galeracluster.md) *This page is licensed: CC BY-SA / Gnu FDL* {% @marketo/form formId="4316" %}
