Reference: http://fedoraproject.org/wiki/Upgrading_Fedora_using_yum#Fedora_16_-.3E_Fedora_17

(1) import the gpg key

Rpm -- import https://fedoraproject.org/static/1ACA3465.txt

(2) install and update dracut

Yum update dracut

(3) convert existing file systems

dracut --force --add convertfs

(4) Modify/etc/grub2.cfg

Cp/etc/grub2.cfg/etc/grub2.cfg. bak

Addrw rd.info rd.convertfs enforcing=0Option and delete the ro rhgb Option

(5) restart and check whether the following directories are links to ensure that the fracut conversion is successful (this step is very important. If the conversion is not successful, the update will be tragic)

/Bin →/usr/bin

/Sbin →/usr/sbin

/Lib →/usr/lib

/Lib64 →/usr/lib64

Check the log:

# Dmesg | grep dracut

(6) update now

# Yum -- releasever = 17 update rpm # rm-f/var/lib/rpm/_ * # rpm -- rebuilddb # yum -- releasever = 17 -- disableplugin = presto distro-sync # fixfiles onboot

In case of a conflict, you can delete these packages before upgrading. Downloading a software package requires 3-4 GB disk space.
