Fedora 22 Upgrade From 21 using FedUp
This is guide, howto upgrade Fedora 21 to Fedora 22 using FedUp.
I have tested this method on several machines, but if you have problems, please let me know. Always remember backup, before upgrade!
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.

su - ## OR ## sudo -i
2.2 Update Fedora 21 Packages
2.3 Reboot Your System
Just make sure that you are running latest kernel.
2.4 Install/Update FedUp
It’s probably installed already.
yum install fedup fedora-release
2.4 Start Upgrading Using FedUp
