upgrading FC5-i386 to FC6-x86_64

[John Poelstra <poelstra redhat com>]

I have a 64bit box that I've been running the i386 install of FC5 on.  Now I'd like to upgrade (not reinstall) it to the x86_64 version of FC6.  I'm guessing this isn't something that is supported, but on the other hand I thought it might work.

Anybody know if this will work or have any other thoughts?

Thanks,
John
