This page includes details for upgrading from [MariaDB 10.11](/docs/release-notes/community-server/10.11/what-is-mariadb-1011.md) to the subsequent long-term maintenance version, [MariaDB 11.4](/docs/release-notes/community-server/11.4/what-is-mariadb-114.md). ### 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 Galera Cluster](/docs/galera-cluster/galera-management/upgrading-galera-cluster.md) section. 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/mariadb-backup-overview.md). The suggested upgrade procedure is: 1. Modify the repository configuration, so the system's package manager installs MariaD11.4. 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-dnf) 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 10.11 and 11.4 On most servers upgrading from 10.11 should be painless. However, there are some things that have changed which could affect an upgrade: #### Options That Have Been Removed or Renamed The following options should be removed or renamed 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. | | [innodb\_defragment](/docs/server/server-usage/storage-engines/innodb/innodb-system-variables.md#innodb_defragment) | [Defragmenting InnoDB Tablespaces](/docs/server/ha-and-performance/optimization-and-tuning/optimizing-tables/defragmenting-innodb-tablespaces.md) in this manner no longer supported. | | [innodb\_defragment\_fill\_factor](/docs/server/server-usage/storage-engines/innodb/innodb-system-variables.md#innodb_defragment_fill_factor) | [Defragmenting InnoDB Tablespaces](/docs/server/ha-and-performance/optimization-and-tuning/optimizing-tables/defragmenting-innodb-tablespaces.md) in this manner no longer supported. | | [innodb\_defragment\_fill\_factor\_n\_recs](/docs/server/server-usage/storage-engines/innodb/innodb-system-variables.md#innodb_defragment_fill_factor_n_recs) | [Defragmenting InnoDB Tablespaces](/docs/server/ha-and-performance/optimization-and-tuning/optimizing-tables/defragmenting-innodb-tablespaces.md) in this manner no longer supported. | | [innodb\_defragment\_frequency](/docs/server/server-usage/storage-engines/innodb/innodb-system-variables.md#innodb_defragment_frequency) | [Defragmenting InnoDB Tablespaces](/docs/server/ha-and-performance/optimization-and-tuning/optimizing-tables/defragmenting-innodb-tablespaces.md) in this manner no longer supported. | | [innodb\_defragment\_n\_pages](/docs/server/server-usage/storage-engines/innodb/innodb-system-variables.md#innodb_defragment_n_pages) | [Defragmenting InnoDB Tablespaces](/docs/server/ha-and-performance/optimization-and-tuning/optimizing-tables/defragmenting-innodb-tablespaces.md) in this manner no longer supported. | | [innodb\_defragment\_stats\_accuracy](/docs/server/server-usage/storage-engines/innodb/innodb-system-variables.md#innodb_defragment_stats_accuracy) | [Defragmenting InnoDB Tablespaces](/docs/server/ha-and-performance/optimization-and-tuning/optimizing-tables/defragmenting-innodb-tablespaces.md) in this manner no longer supported. | #### Options That Have Changed Default Values | Option | Old default | New default | | --------------------------------------------------------------------------------------------------------------------------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------ | | [optimizer\_switch](/docs/server/server-management/variables-and-modes/server-system-variables.md#optimizer_switch) | | See [optimizer-switch](/docs/server/ha-and-performance/optimization-and-tuning/query-optimizations/optimizer-switch.md). | | [innodb\_purge\_batch\_size](/docs/server/server-usage/storage-engines/innodb/innodb-system-variables.md#innodb_purge_batch_size) | 300 | 1000 | #### Options That Have Been Removed or Renamed The following options should be removed or renamed 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 | | ------------------------------------------------------------------------------------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------- | | [old\_alter\_table](/docs/server/server-management/variables-and-modes/server-system-variables.md#old_alter_table) | Superseded by [alter\_algorithm](/docs/server/server-management/variables-and-modes/server-system-variables.md#alter_algorithm). | #### 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 | | ------------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [innodb\_purge\_rseg\_truncate\_frequency](/docs/server/server-usage/storage-engines/innodb/innodb-system-variables.md#innodb_purge_rseg_truncate_frequency) | The motivation for introducing this in MySQL seems to have been to avoid stalls due to freeing undo log pages or truncating undo log tablespaces. In MariaDB, [innodb\_undo\_log\_truncate=ON](/docs/server/server-usage/storage-engines/innodb/innodb-system-variables.md#innodb_undo_log_truncate) should be a much lighter operation because it will not involve any log checkpoint, hence this is deprecated and ignored | | [tx\_isolation](/docs/server/server-management/variables-and-modes/server-system-variables.md#tx_isolation) | Replaced with [transaction\_isolation](/docs/server/server-management/variables-and-modes/server-system-variables.md#transaction_isolation) to align the option and system variable. | | [tx\_read\_only](/docs/server/server-management/variables-and-modes/server-system-variables.md#tx_read_only) | Replaced with [transaction\_read\_only](/docs/server/server-management/variables-and-modes/server-system-variables.md#transaction_read_only) to align the option and system variable. | ### 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) * [Features in MariaDB 11.2](/docs/release-notes/community-server/old-releases/11.2/what-is-mariadb-112.md) * [Features in MariaDB 11.1](/docs/release-notes/community-server/old-releases/11.1/what-is-mariadb-111.md) * [Features in MariaDB 11.0](/docs/release-notes/community-server/old-releases/11.0/what-is-mariadb-110.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) * [Upgrading from MariaDB 10.6 to MariaDB 10.11](/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.md) * [Upgrading from MariaDB 10.5 to MariaDB 10.6](/docs/server/server-management/install-and-upgrade-mariadb/upgrading/mariadb-community-server-upgrade-paths/upgrading-from-mariadb-10-5-to-mariadb-10-6.md) *This page is licensed: CC BY-SA / Gnu FDL* {% @marketo/form formId="4316" %}
