Fedora-vertical-logoThis is guide, howto upgrade Fedora 23 to Fedora 24 using DNF.

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 step, because if something goes wrong and you have to do fresh install, then you can easily restore your data.

2. Upgrade Fedora 23 to Fedora 24 using DNF

2.1 Change root user


su -
## OR ##
sudo -i

2.2 Update Fedora 23 Packages


dnf update

2.3 Reboot Your System

Just make sure that you are running latest kernel.


reboot

2.4 Install/Update dnf-plugin-system-upgrade package

It’s probably installed already.


dnf install dnf-plugin-system-upgrade --best

2.5 Start Upgrading Using DNF


dnf system-upgrade download --releasever=24

When this finish, check if there is any errors. You might need

--best

and

--allowerasing

options to get all packages downloaded.

Use rpmconf to find .rpmnew, .rpmsave and .rpmorig files. You can keep current version, place back old version, watch the diff or merge.


dnf install rpmconf

rpmconf -a
