Upgrade/Update Fedora 16 to 17

Today, I upgrade my fedora 16 to 17 on my laptop Fujitsu SH561.
There is some note about updating process.

1. Dump or back up your data first to ensure you can recover when issue occurred.

2. Get root permission
 
    # yum update
    # yum clean all
    # yum install preupgrade
    # preupgrade

After you make command "preupgrade", GUI upgrade GUI program will lead you finish upgrade process.
Or your can do this command by CLI.

# preupgrade-cli "Fedora 17 (Beefy Miracle)"

(It will take a period of long time and reboot your OS, be patient)
