Upgrading from MariaDB 10.5 to MariaDB 10.6

How to Upgrade

For Windows, see 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 Mariabackup.

The suggested upgrade procedure is:

  1. Modify the repository configuration, so the system's package manager installs MariaDB 10.6. For example,
  2. Stop MariaDB.
  3. 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
  4. Install the new version of MariaDB.
  5. Make any desired changes to configuration options in option files, such as my.cnf. This includes removing any options that are no longer supported.
  6. Start MariaDB.
  7. Run mariadb-upgrade.
    • mariadb-upgrade does two things:
      1. Ensures that the system tables in the mysql 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 10.5 and 10.6

On most servers upgrading from 10.5 should be painless. However, there are some things that have changed which could affect an upgrade:

Reserved Word

InnoDB COMPRESSED Row Format

From MariaDB 10.6.0, tables that are of the COMPRESSED row format are read-only by default. This is the first step towards removing write support and deprecating the feature.

Set the innodb_read_only_compressed variable to OFF to make the tables writable.
