I'm currently running MySQL 3.23.x and PHP 4.0.x on the Red Hat Linux 6.1
If I want to upgrade MySQL and PHP to the latest version, do I just re-install the software according to the INSTALL file as a brand new installation?
Or do I need to uninstall the old versions first?
I'm not familiar with this sort of upgrade, I can't find documentation related to UPGRADE procedure.
Is there some related information available on the web?
