For MariaDB Galera Cluster, see [[upgrading-from-mariadb-107-to-mariadb-108-with-galera-cluster|Upgrading from MariaDB 10.7 to MariaDB 10.8 with Galera Cluster]] instead.

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 [[installing-mariadb-deb-files/#updating-the-mariadb-apt-repository-to-a-new-major-release|Updating the MariaDB APT repository to a New Major Release]] for more information.
** On RHEL, CentOS, Fedora, and other similar Linux distributions, see [[yum/#updating-the-mariadb-yum-repository-to-a-new-major-release|Updating the MariaDB YUM repository to a New Major Release]] for more information.
** On SLES, OpenSUSE, and other similar Linux distributions, see [[installing-mariadb-with-zypper/#updating-the-mariadb-zypp-repository-to-a-new-major-release|Updating the MariaDB ZYpp repository to a New Major Release]] for more information.
# [[starting-and-stopping-mariadb-automatically|Stop MariaDB]].
# Uninstall the old version of MariaDB.
** On Debian, Ubuntu, and other similar Linux distributions, execute the following: \\
<<code>>sudo apt-get remove mariadb-server<</code>>
** On RHEL, CentOS, Fedora, and other similar Linux distributions, execute the following: \\
<<code>>sudo yum remove MariaDB-server<</code>>
** On SLES, OpenSUSE, and other similar Linux distributions, execute the following: \\
<<code>>sudo zypper remove MariaDB-server<</code>>
# Install the new version of MariaDB.
** On Debian, Ubuntu, and other similar Linux distributions, see [[installing-mariadb-deb-files/#installing-mariadb-packages-with-apt|Installing MariaDB Packages with APT]] for more information.
** On RHEL, CentOS, Fedora, and other similar Linux distributions, see [[yum/#installing-mariadb-packages-with-yum|Installing MariaDB Packages with YUM]] for more information.
** On SLES, OpenSUSE, and other similar Linux distributions, see [[installing-mariadb-with-zypper/#installing-mariadb-packages-with-zypp|Installing MariaDB Packages with ZYpp]] for more information.
# Make any desired changes to configuration options in [[configuring-mariadb-with-option-files|option files]], such as ##my.cnf##. This includes removing any options that are no longer supported.
# [[starting-and-stopping-mariadb-automatically|Start MariaDB]].
# Run [[mariadb-upgrade]].
** ##mariadb-upgrade## does two things:
### Ensures that the system tables in the [[the-mysql-database-tables|mysql]] database are fully compatible with the new version.
### 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 Been Removed or Renamed
The following options should be removed or renamed if you use them in your [[configuring-mariadb-with-option-files|option files]]:

<<style class="darkheader-nospace-borders">>
|= Option |= Reason
| [[innodb-system-variables/#innodb_log_write_ahead_size|innodb_log_write_ahead_size]] | On Linux and Windows, the physical block size of the underlying storage is instead detected and used. 
<</style>>

==== 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.

=== 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 [[create-procedure/#inoutinout|IN, OUT and INOUT]] parameter qualifiers. Added as well for [[create-function/#in-out-inout-in-out|stored functions]] and (IN only) [[declare-cursor/#in|cursors]] (MDEV-10654).
* Individual columns in the [[optimization-and-indexes|index]] can now be explicitly sorted in the ascending or descending order. This can be useful for optimizing certain [[order-by|ORDER BY]] cases (MDEV-13756, MDEV-26938, MDEV-26939,  MDEV-26996).
* See also [[system-variables-added-in-mariadb-10-8/|System Variables Added in MariaDB 10.8]].
