This is guide, howto upgrade Fedora 17 to Fedora 18 (Spherical Cow) using YUM. Old official Preupgrade method is not available anymore on Fedora 18/17, it’s replaced by new FedUp method, which is official method to upgrade Fedora 17 to Fedora 18 or rawhide.

I have tested this method, but if you have problems, please let me know.

1. Before Upgrade

1.1 Backup Your Data

Before doing anything, do full system backup or backup at least your important data: documents, pictures, videos, config files, log files, databases etc. This is very important, because if something go wrong and you have to do fresh install, then you can easily restore your data.

2. Upgrade Fedora 17 to Fedora 18

2.1 Change root user

su -
## OR ##
sudo -i

2.2 Update Fedora 17 Packages

yum update

2.3 Reboot Your System

Just make sure that you are running latest kernel.


2.4 Install FedUp

It’s probably installed already.

yum install fedup

2.4 Start Upgrading Using FedUp

fedup-cli --network 18 --debuglog /root/fedup.debug.log

When this finish, check if there is any errors in fedup.debug.log.

You can enable additional repos, with using following option:

--enablerepo REPO
