So... what is the easiest way to convert my 32 bit installation to 64 bits ? Please don't tell me to reinstall because I just did that earlier this week to go from F9 back to F8.
sorry - reinstall is your only option
Depends how crazy you are feeling but I would suggest doing a reinstall. If you really really want you can force install (with rpm --forcearch) parallel 64bit versions of the core setup but its pretty hairy.
