We have several servers that we have been running FC4 i386 even though they are AMD x64 based servers.
Since the x64 distro seems to have stabilized and, from what I understand, it is rather solid, I started wondering how to get what we paid for out of these nice x64 processors.
So, is it possible to "upgrade" to the x64 distro from the i386 version (via the installer or something)?
What would be more appealing, of course, would be a "live" update method similar to what is defined in http://fedoraproject.org/wiki/YumUpgradeFaq
which would only result in the downtime necessary to reboot the server...
It's really just a wishful thought that is being tossed around, but it would be awesome to make it become a reality.
