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!
- 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.
