# Upgrading from MariaDB 10.6 to MariaDB 10.7 Note that [MariaDB 10.7](https://app.gitbook.com/s/aEnK0ZXmUbJzqQrTjFyb/community-server/old-releases/10.7/what-is-mariadb-107) is [only maintained for one year](https://mariadb.org/about/#maintenance-policy). [MariaDB 10.6](https://app.gitbook.com/s/aEnK0ZXmUbJzqQrTjFyb/community-server/10.6/what-is-mariadb-106) is currently the latest long-term maintenance release. ### 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 10.7 with Galera Cluster](https://github.com/mariadb-corporation/docs-server/blob/test/server/server-management/getting-installing-and-upgrading-mariadb/upgrading/upgrading-to-unmaintained-mariadb-releases/upgrading-from-mariadb-106-to-mariadb-107-with-galera-cluster/README.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](https://mariadb.com/docs/server/server-usage/backup-and-restore/mariadb-backup/mariadb-backup-overview). The suggested upgrade procedure is: 1. Modify the repository configuration, so the system's package manager installs [MariaDB 10.7](https://app.gitbook.com/s/aEnK0ZXmUbJzqQrTjFyb/community-server/old-releases/10.7/what-is-mariadb-107). 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 10.6 and 10.7 On most servers upgrading from 10.6 should be painless. However, there are some things that have changed which could affect an upgrade: #### Reserved Words * ROW\_NUMBER is now a [reserved word](https://mariadb.com/docs/server/reference/sql-structure/sql-language-structure/reserved-words). #### Compression If a non-zlib compression algorithm was used in [InnoDB](https://mariadb.com/docs/server/server-usage/storage-engines/innodb) or [Mroonga](https://mariadb.com/docs/server/server-usage/storage-engines/mroonga) before upgrading to 10.7, those tables will be unreadable until the appropriate compression library is installed. See [Compression Plugins#Upgrading](https://mariadb.com/docs/server/ha-and-performance/optimization-and-tuning/optimization-and-tuning-compression/compression-plugins#upgrading). #### Options That
