Fedora-vertical-logoThis 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.

2. Upgrade Fedora 21 to Fedora 22 using FedUp

2.1 Change root user


su -
## OR ##
sudo -i

2.2 Update Fedora 21 Packages


yum update

2.4 Install/Update FedUp

It’s probably installed already.


yum install fedup fedora-release

2.4 Start Upgrading Using FedUp


fedup-cli --network 22 --debuglog /root/fedup-21to22.debug.log

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