# Upgrading from MariaDB 10.7 to MariaDB 10.8 ### 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). 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 10.8](https://app.gitbook.com/s/aEnK0ZXmUbJzqQrTjFyb/community-server/old-releases/10.8/what-is-mariadb-108). 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 10.7 and 10.8 On most servers upgrading from 10.7 should be painless. However, there are some things that have changed which could affect an upgrade: #### Options That Have Changed Default Values | Option | Old default value | New default value | | -------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------- | ----------------- | | [innodb\_buffer\_pool\_chunk\_size](https://mariadb.com/docs/server/server-usage/storage-engines/innodb/innodb-system-variables#innodb_buffer_pool_chunk_size) | 134217728 | Autosized | | [spider\_semi\_table\_lock](https://mariadb.com/docs/server/server-usage/storage-engines/spider/spider-system-variables) | 1 | 0 | #### Options That Have Been Removed or Renamed The following options should be removed or renamed if you use them in your [option files](https://mariadb.com/docs/server/server-management/install-and-upgrade-mariadb/configuring-mariadb/configuring-mariadb-with-option-files): | Option | Reason | | ---------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------- | | [innodb\_log\_write\_ahead\_size](https://mariadb.com/docs/server/server-usage/storage-engines/innodb/innodb-system-variables#innodb_log_write_ahead_size) | On Linux and Windows, the physical block size of the underlying storage is instead detected and used. | #### Deprecated Options The following options have been deprecated. They have not yet been removed, but will be in a future version, and should ideally no longer be used. | Option | Reason | | --------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------- | | [keep\_files\_on\_create](https://mariadb.com/docs/server/variables-and-modes/server-system-variables#keep_files_on_create) | MariaDB now deletes orphan files, so this setting should never be necessary. | ### Major New Features To Consider You might consider using the following major new features in [MariaDB 10.8](https://app.gitbook.com/s/aEnK0ZXmUbJzqQrTjFyb/community-server/old-releases/10.8/what-is-mariadb-108): * Stored procedures already have support for the [IN, OUT and INOUT](https://mariadb.com/docs/server/server-usage/stored-routines/stored-procedures/create-procedure#inoutinout) parameter qualifiers. Added as well for [stored functions](https://mariadb.com/docs/server/reference/sql-statements/data-definition/create/create-function#in-out-inout-in-out) and (IN only) [cursors](https://mariadb.com/docs/server/reference/sql-statements/programmatic-compound-statements/programmatic-compound-statements-cursors/declare-cursor#in) ([MDEV-10654](https://jira.mariadb.org/browse/MDEV-10654)). * Individual columns in the [index](https://mariadb.com/docs/server/ha-and-performance/optimization-and-tuning/optimization-and-indexes) can now be explicitly sorted in the ascending or descending order. This can be useful for optimizing certain [ORDER BY](https://mariadb.com/docs/server/reference/sql-statements/data-manipulation/selecting-data/order-by) cases ([MDEV-13756](https://jira.mariadb.org/browse/MDEV-13756), [MDEV-26938](https://jira.mariadb.org/browse/MDEV-26938), [MDEV-26939](https://jira.mariadb.org/browse/MDEV-26939), [MDEV-26996](https://jira.mariadb.org/browse/MDEV-26996)). * See also [System Variables Added in MariaDB 10.8](https://mariadb.com/docs/server/ha-and-performance/optimization-and-tuning/system-variables/system-and-status-variables-added-by-major-release/system-and-status-variables-added-by-major-unmaintained-release/system-variables-added-in-mariadb-10-8). ### See Also * [The features in MariaDB 10.8](https://app.gitbook.com/s/aEnK0ZXmUbJzqQrTjFyb/community-server/old-releases/10.8/what-is-mariadb-108) * [Upgrading from MariaDB 10.7 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-107-to-mariadb-108-with-galera-cluster/README.md) * [Upgrading from MariaDB 10.6 to MariaDB 10.7](https://mariadb.com/docs/server/server-management/install-and-upgrade-mariadb/upgrading/mariadb-community-server-upgrade-paths/upgrading-to-unmaintained-mariadb-releases/upgrading-from-mariadb-10-6-to-mariadb-10-7) * [Upgrading from MariaDB 10.5 to MariaDB 10.6](https://mariadb.com/docs/server/server-management/install-and-upgrade-mariadb/upgrading/mariadb-community-server-upgrade-paths/upgrading-from-mariadb-10-5-to-mariadb-10-6) * [Upgrading from MariaDB 10.4 to MariaDB 10.5](https://mariadb.com/docs/server/server-management/install-and-upgrade-mariadb/upgrading/mariadb-community-server-upgrade-paths/upgrading-to-unmaintained-mariadb-releases/upgrading-from-mariadb-10-4-to-mariadb-10-5) *This page is licensed: CC BY-SA / Gnu FDL* {% @marketo/form formId="4316" %}
