Fedora Core -> CentOS and Plesk using yum

[breun]

I know it's possible to change a Fedora Core 3 machine to a CentOS 4.3 machine using yum (see http://harryh.homelinux.org/?p=69 for instance). I wonder if Plesk would survive such an upgrade however. I am planning on testing this in VMware, but if someone already tried and knows it won't work I won't bother trying.
