Before You Begin
cPanel and WHM can only be installed on a blank server with a fresh operating system install. No data should be on the server that you wish to keep. This includes, but is not limited to, web pages, configuration files, user accounts and scripts. The installer will make many changes to your system including the downloading and configuring of needed packages for you. Because of the considerable amount of changes that cPanel will make to the system, the suggested method of uninstalling the cPanel and WHM software is to reformat the server.
