vendor ($vendor) than $myvendor. Some files may be installed
to different locations, including log files and the service
startup script in %{_sysconfdir}/init.d/.

Upgrading directly from MySQL $old_family to MariaDB $new_family may not
be safe in all cases. A manual dump and restore using mysqldump is
recommended. It is important to review the MariaDB manual's Upgrading
section for version-specific incompatibilities.

******************************************************************
A MySQL or MariaDB server package ($installed) is installed.
$error_text
A manual upgrade is required.
- Ensure that you have a complete, working backup of your data and my.cnf
files
- Shut down the MySQL server cleanly
- Remove the existing MySQL packages. Usually this command will
list the packages you should remove:
rpm -qa | grep -i '^mysql-'
You may choose to use 'rpm --nodeps -ev <package-name>' to remove
the package which contains the mysqlclient shared library. The
library will be reinstalled by the MariaDB-shared package.
- Install the new MariaDB packages supplied by $myvendor
- Ensure that the MariaDB server is started
- Run the 'mysql_upgrade' program
This is a brief description of the upgrade process. Important details
can be found in the MariaDB manual, in the Upgrading section.
