Replacing MySQL on Centos 6 that is also running Plesk?

I have a new Centos 6 server that is running Plesk for the control panel. That's how it came, I'm not crazy about it but trying to work with it.

I want to replace MySQL and use MariaDB

I think the main issue is that Plesk has rename the root user to admin.

I was going to uninstall MySQL and install MariaDB but isn't it going to want to know the password for root???

IIRC, the RPM packages don't prompt you to update or change the MariaDB/MySQL root user password during installs and upgrades.

The DEB packages do, but the DEB packages also have a special database upgrade user that is created during the initial install for doing just this sort of thing (changing the MariaDB root user password).
