Re: Upgrade FC5 x86_64 to FC6_x86?

I'd be *very* wary about trying that. For one thing, the installer will
almost certainly run RPM pre-uninstall scripts
(http://www.rpm.org/max-rpm/s1-rpm-erase-erasing-package.html) if any
packages are replaced. Those pre-uninstall scripts are allowed to make
use of existing binaries in the package -- except they'll be 64 bit
binaries, which Just Won't Run under a 32 bit installer.

So you can expect to break a few RPMs on the upgrade.

I imagine that nearly all 64 bit RPMs that aren't upgraded will be
removed anyway (the 64 bit kernel might remain). Any left will be
useless and potentially confusing.

I'm not even convinced that the installer would even try upgrading a
different architecture. It's certainly not something that would have
received widespread testing.

If you *want* to test it, and report any breakages to Bugzilla, go
ahead. You should be familiar with troubleshooting Linux problems, using
RPM and other tools to diagnose package problems, and using the rescue
CD to reinstall or remove packages if necessary. You should also have
alternative ways of accessing the Internet and getting packages to the
PC, and plenty of time to spend if necessary. And you should not expect
to use this PC for any work for a couple of weeks, and be prepared to
re-install *anyway* if things go too badly wrong.

Otherwise, just re-install and save yourself the headache!

Hope this helps,

James.
