Upgrading to Fedora 7 from Live CD?

[Pierre Sarrazin]

Hi. Is it possible to upgrade to Fedora 7 from the Live CD?

I'm trying to upgrade a CD-only Fedora 5 machine to Fedora 7.
Clicking on the "Install to Hard Drive" icon starts the Fedora
Installer, which only offers to do a fresh install, but not an
upgrade.

If the Live CD does not support upgrading, then how can I
reliably upgrade a Fedora 5 system on a CD-only machine?

Thanks.
