The current MariaDB server package is provided by a different

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.
