I've done searching for this issue, and found these instructions:
but - I don't have the file check_cpanel_rpms on my server. My WHM is 18.104.22.168 according to the top left (though before i tried the upgrade it said 11.28..).. and i have the message that says the upgrade was blocked. is there another file I'm supposed to use?
You can try the following steps: 1. Modify the /var/cpanel/cpanel.config file so that the following line exists: mysql-version=5.1 Note that you should modify the "mysql-version" entry to 5.1 if an entry for 5.0 already exists. 2. Run the following command: /scripts/check_cpanel_rpms It should prompt you to update the MySQL RPMs. Keep in mind that you should backup your existing databases before upgrading to a new version of MySQL.
