### How to Upgrade

For Windows, see [Upgrading MariaDB on Windows](https://mariadb.com/docs/server/server-management/install-and-upgrade-mariadb/upgrading/platform-specific-upgrade-guides/upgrading-mariadb-on-windows).

For MariaDB Galera Cluster, see [Upgrading from MariaDB 10.6 to MariaDB 10.11 with Galera Cluster](https://app.gitbook.com/s/3VYeeVGUV4AMqrA3zwy7/galera-management/upgrading-galera-cluster/upgrading-from-mariadb-10-6-to-mariadb-10-11-with-galeracluster) 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](https://github.com/mariadb-corporation/mariadb-docs/blob/main/server/server-usage/backing-up-and-restoring-databases/mariadb-backup/README.md).

The suggested upgrade procedure is:

1. Modify the repository configuration, so the system's package manager installs [MariaDB 11.4](https://app.gitbook.com/s/aEnK0ZXmUbJzqQrTjFyb/community-server/mariadb-11-4-series/what-is-mariadb-114). For example,

* On Debian, Ubuntu, and other similar Linux distributions, see [Updating the MariaDB APT repository to a New Major Release](https://mariadb.com/docs/server/server-management/installing-mariadb/binary-packages/installing-mariadb-deb-files#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](https://mariadb.com/docs/server/server-management/installing-mariadb/binary-packages/rpm/yum#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](https://mariadb.com/docs/server/server-management/installing-mariadb/binary-packages/rpm/installing-mariadb-with-zypper#updating-the-mariadb-zypp-repository-to-a-new-major-release) for more information.

1. [Stop MariaDB](https://mariadb.com/docs/server/server-management/starting-and-stopping-mariadb/starting-and-stopping-mariadb-automatically).
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](https://mariadb.com/docs/server/server-management/installing-mariadb/binary-packages/installing-mariadb-deb-files#installing-mariadb-packages-with-apt) for more information.
* On RHEL, CentOS, Fedora, and other similar Linux distributions, see [Installing MariaDB Packages with YUM](https://mariadb.com/docs/server/server-management/installing-mariadb/binary-packages/rpm/yum#installing-mariadb-packages-with-yum) for more information.
* On SLES, OpenSUSE, and other similar Linux distributions, see [Installing MariaDB Packages with ZYpp](https://mariadb.com/docs/server/server-management/installing-mariadb/binary-packages/rpm/installing-mariadb-with-zypper#installing-mariadb-packages-with-zypp) for more information.

1. Make any desired changes to configuration options in [option files](https://mariadb.com/docs/server/server-management/install-and-upgrade-mariadb/configuring-mariadb/configuring-mariadb-with-option-files), such as `my.cnf`. This includes removing any options that are no longer supported.
2. [Start MariaDB](https://mariadb.com/docs/server/server-management/starting-and-stopping-mariadb/starting-and-stopping-mariadb-automatically).
3. Run [mariadb-upgrade](https://mariadb.com/docs/server/clients-and-utilities/deployment-tools/mariadb-upgrade).

* `mariadb-upgrade` does two things:
  1. Ensures that the system tables in the [mysql](https://mariadb.com/docs/server/reference/system-tables/the-mysql-database-tables) 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 .

### Incompatible Changes Between 11.3 and 11.4
