Upgrading from MariaDB 10.7 to MariaDB 10.8

Note that MariaDB 10.8 is only maintained for one year. MariaDB 10.6 is currently the latest long-term maintenance release.

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:

Modify the repository configuration, so the system's package manager installs MariaDB 10.8. 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 SLES, OpenSUSE, and other similar Linux distributions, see Updating the MariaDB ZYpp repository to a New Major Release for more information.
Stop MariaDB.
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
Install the new version of MariaDB.
- On Debian, Ubuntu, and other similar Linux distributions, see Installing MariaDB Packages with APT for more information.
- On RHEL, CentOS, Fedora, and other similar Linux distributions, see Installing MariaDB Packages with YUM for more information.
- On SLES, OpenSUSE, and other similar Linux distributions, see Installing MariaDB Packages with ZYpp for more information.
Make any desired changes to configuration options in option files, such as my.cnf. This includes removing any options that are no longer supported.
Start MariaDB.
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 10.7 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	134217728	Autosized
spider_semi_table_lock	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:

Option	Reason
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	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:

Stored procedures already have support for the IN, OUT and INOUT parameter qualifiers. Added as well for stored functions and (IN only) cursors (MDEV-10654).
Individual columns in the index can now be explicitly sorted in the ascending or descending order. This can be useful for optimizing certain ORDER BY cases (MDEV-13756, MDEV-26938, MDEV-26939, MDEV-26996).
