Learn how to upgrade MariaDB Server. This section provides detailed instructions and best practices for performing seamless and safe upgrades to newer versions.
Guide to upgrading MariaDB on Linux.
Provides tailored instructions for upgrading MariaDB on different operating systems, including Linux and Windows, and within specific environments like Galera Cluster.
An overview of supported upgrade paths for MariaDB Community Server, linking to specific guides for upgrading between major versions like 10.x and 11.x.
Upgrading guides for unmaintained versions of MariaDB Community Server.
Steps for minor version upgrades (e.g., 10.5.8 to 10.5.9) on Linux, which typically involve package manager updates and a service restart.
For Windows, see Upgrading MariaDB on Windows 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.
To upgrade between minor versions of MariaDB on Linux/Unix (for example from MariaDB 10.11.4 to MariaDB 10.11.5), the following procedure is suggested:
Stop MariaDB.
Uninstall the old version of MariaDB.
Install the new version of MariaDB.
On Debian, Ubuntu, and other similar Linux distributions, see for more information.
On RHEL, CentOS, Fedora, and other similar Linux distributions, see for more information.
On SLES, OpenSUSE, and other similar Linux distributions, see for more information.
Make any desired changes to configuration options in , such as my.cnf.
Start MariaDB.

Guide to upgrading MariaDB on Windows using the MSI installer, supporting both minor upgrades and major version migrations using the upgrade wizard.
For incompatibilities such as removed features, and changes to variables, see the pages describing changes by version on Upgrading MariaDB.
To install a minor upgrade with MSI, just download the MSI and install it. It will do everything that needs to be done for minor upgrade automatically - shutdown MariaDB service(s), replace executables and DLLs, and start service(s) again.
The rest of the article is dedicated to major upgrades, e.g 10.1.x to 10.2.y.
This section assumes MSI installations.
First, check everything listed in the Incompatibilities section of the article relating to the version you are upgrading, for example, , to make sure you are prepared for the upgrade.
MariaDB (and also MySQL) allows different versions of the product to co-exist on the same machine, as long as these versions are different either in major or minor version numbers. For example, it is possible to have say and 5.2.6 to be installed on the same machine.
However only a single instance of 5.2 can exist. If for example 5.2.7 is installed on a machine where 5.2.6 is already installed, the installer will just replace 5.2.6 executables with 5.2.7 ones.
Now imagine, that both 5.1 and 5.2 are installed on the same machine and we want to upgrade the database instance running on 5.1 to the new version. In this case special tools are requied. Traditionally, is used to accomplish this. On Windows, the is a complicated multiple-step manual process.
Since , the Windows distribution includes tools that simplify migration between different versions and also allow migration between MySQL and MariaDB.
Note. Automatic upgrades are only possible for DB instances that run as a Windows service.
Important: Ignore any statement that tells you to "just uninstall MySQL and install MariaDB". This does not work on Windows, never has, and never will. Keep your MySQL installed until after the database had been converted.
The following install/upgrade sequence is recommended in case of "major" upgrades, like going from 5.3 to 5.5
Install new version, while still retaining the old one
Upgrade services one by one, like described later in the document (e.g with mysql_upgrade_service). It is recommeded to have services cleanly shut down before the upgrade.
Uninstall old version when previous step is done.
Note. This recommendation differs from the procedure on Unixes, where the upgrade sequence is "uninstall old version, install new version"
This is a GUI tool that is typically invoked at the end of a MariaDB installation if upgradable services are found. The UI allows you to select instances you want to upgrade.
mysql_upgrade_serviceThis is a command line tool that performs upgrades. The tool requires full administrative privileges (it has to start and stop services).
Example usage:
mysql_upgrade_service accepts a single parameter —
the name of the MySQL or MariaDB service. It performs all the steps to convert
a MariaDB/MySQL instance running as the service to the current version.
Earlier we said that only single instance of "MariaDB ." version can be installed on the same machine. This was almost correct, because MariaDB MSI installations allow 32 and 64-bit versions to be installed on the same machine, and in this case it is possible to have two instances of say 5.2 installed at the same time, an x86 one and an x64 one. One can use the x64 Upgrade wizard to upgrade an instance running as a 32-bit process to run as 64-bit.
Both UpgradeWizard and mysql_upgrade_service can also be used to upgrade database instances that were installed with the .

General instructions for performing major version upgrades (e.g., 10.3 to 10.4) on Linux, covering repository updates, backup recommendations, and using `mariadb-upgrade`.
MariaDB is designed to allow easy upgrades. You should be able to trivially upgrade from ANY earlier MariaDB version to the latest one (for example .x to .x), usually in a few seconds. This is also mainly true for any MySQL version < 8.0 to and up.
Upgrades are normally easy because:
All MariaDB table data files are backward compatible
The MariaDB connection protocol is backward compatible. You don't normally need to upgrade any of your old clients to be able to connect to a newer MariaDB version.
Modify the repository configuration, so the system's package manager installs . For example,
On Debian, Ubuntu, and other similar Linux distributions, see 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 for more information.

On Debian, Ubuntu, and other similar Linux distributions, execute the following:sudo apt-get remove mariadb-server

The MariaDB replica can be of any newer version than the primary.
MariaDB Corporation regularly runs tests to check that one can upgrade from to the latest MariaDB version without any trouble. All older versions should work too (as long as the storage engines you were using are still around).
Note that if you are using MariaDB Galera Cluster, you have to follow the !
Go through the individual version upgrade notes (listed below) to look for any major changes or configuration options that have changed.
Ensure that the target MariaDB version supports the storage engines you are using. For example, in 10.5 TokuDB is not supported.
Back up the database (just in case). At least, take a copy of the mysql system database directory under the data directory with mariadb-dump --add-drop-table mysql (called mysqldump in and earlier) as most of the upgrade changes are done there (adding new fields and new system tables etc).
Cleanly shutdown the server. This is necessary because even if data files are compatible between versions, recovery logs may not be.
Ensure that the variable is not 2 (fast crash shutdown). The default of this variable is 1.
must be less than 3.
Note that rpms don't support upgrading between major versions, only minor like 10.4.1 to 10.4.2. If you are using rpms, you should de-install the old MariaDB rpms and install the new MariaDB rpms before running mariadb-upgrade. Note that when installing the new rpms, mariadb-upgrade may be run automatically. There is no problem with running mariadb-upgrade many times.
If you have a primary-replica setup, first upgrade one replica and when you have verified that the replica works well, upgrade the rest of the replicas (if any). Then upgrade one replica to primary, upgrade the primary, and change the replica to a primary.
If you don't have a primary-replica setup, then take a backup, shutdown MariaDB and do the upgrade.
Upgrade MariaDB binaries and libraries, preferably without starting MariaDB.
If the MariaDB server process, mariadbd was not started as part of the upgrade, start it by executing mariadbd --skip-grant-tables. This may produce some warnings about some system tables not being up to date, but you can ignore these for now as mariadb-upgrade will fix that.
Run mariadb-upgrade
Restart MariaDB server.
The main work done when upgrading is done by running mariadb-upgrade. The main things it does are:
Updating the system tables in the mysql database to the newest version. This is very quick.
mariadb-upgrade also runs mariadb-check --check-upgrade to check if there have been any collation changes between the major versions. This recreates indexes in old tables that are using any of the changed collations. This can take a bit of time if there are a lot of tables or there are many tables which used the changed collation. The last time a collation changed was in MariaDB/MySQL 5.1.23.
Check the MariaDB error log for any problems during upgrade. If there are any warnings in the log files, do your best to get rid of them!
The common warnings/errors are:
Using obsolete options. If this is the case, remove them from your my.cnf files.
Check the manual for new features that have been added since your last MariaDB version.
Test that your application works as before. The main difference from before is that because of optimizer improvements your application should work better than before, but in some rare cases the optimizer may get something wrong. In this case, you can try to use explain, or optimizer_switch to fix the queries.
First, check the MariaDB error log to see if you are using configure options that are not supported anymore.
Check the upgrade notices for the MariaDB release that you are upgrading to.
File an issue in the so that we know about the issue and can provide a fix to make upgrades even better.
Add a comment to this manual entry for how we can improve it.
In the unlikely event something goes wrong, you can try the following:
Remove the InnoDB tables from the mysql data directory. They are:
gtid_slave_pos
innodb_table_stats
innodb_index_stats
transaction_registry
Move the mysql data directory to mysql-old and run to generate a new one.
After the above, you have to add back your old users.
When done, delete the mysql-old data directory.
MariaDB server is not designed for downgrading. That said, in most cases, as long as you haven't run any ALTER TABLE or CREATE TABLE statements and you have a mariadb-dump of your old mysql database , you should be able to downgrade to your previous version by doing the following:
Do a clean shutdown. For this special case you have to set innodb_fast_shutdown to 0,before taking down the new MariaDB server, to ensure there are no redo or undo logs that need to be applied on the downgraded server.
Delete the tables in the mysql database (if you didn't use the option --add-drop-table to mariadb-dump)
Delete the new MariaDB installation

innodb_adaptive_checkpoint; Use innodb_adaptive_flushing_method instead.
innodb_auto_lru_dump; Use innodb_buffer_pool_restore_at_startup instead (and innodb_buffer_pool_load_at_startup in ).

↑ If using a MariaDB apt or yum repository, it is often enough to replace instances of '5.3' with '5.5' and then run an update/upgrade. For example, in Ubuntu/Debian update the MariaDB sources.list entry from something that looks similar to this:
To something like this:
And then run
And in Red Hat, CentOS, and Fedora, change the baseurl line from something that looks like this:

On most servers upgrading from 10.4 should be painless. However, there are some things that have changed which could affect an upgrade:
All binaries previously beginning with mysql now begin with mariadb, with symlinks for the corresponding mysql command.
Usually that shouldn't cause any changed behavior, but when starting the MariaDB server via , or via the script symlink, the server process will now always be started as mariadbd, not mysqld.
So anything looking for the mysqld name in the system process list, like e.g. monitoring solutions, now needs for mariadbd instead when the server / service is not started directly, but via mysqld_safe or as a system service.
A number of statements changed the privileges that they require. The old privileges were historically inappropriately chosen in the upstream. 10.5.2 fixes this problem. Note, these changes are incompatible to previous versions. A number of GRANT commands might be needed after upgrade.
SHOW BINLOG EVENTS now requires the BINLOG MONITOR privilege (requred REPLICATION SLAVE prior to 10.5.2).
SHOW SLAVE HOSTS now requires the REPLICATION MASTER ADMIN privilege (required REPLICATION SLAVE prior to 10.5.2).

On most servers upgrading from 10.1 should be painless. However, there are some things that have changed which could affect an upgrade:
uses InnoDB as the default storage engine, rather than XtraDB, used in and before. See Why does MariaDB 10.2 use InnoDB instead of XtraDB? In most cases this should have minimal effect as the latest InnoDB has incorporated most of the improvements made in earlier versions of XtraDB. Note that certain XtraDB system variables are now ignored (although they still exist so as to permit easy upgrading).
In particular, take note of the changes to innodb_strict_mode, sql_mode, binlog_format, binlog_checksum and innodb_checksum_algorithm.
