Upgrade from Fedora 24 to Fedora 25 with DNF
If you are a Fedora power user you can do it by DNF Upgrade plugin. The upgrade process from Fedora 24 to Fedora 25 is pretty simple, but you need to run a few commands on the terminal.
First of all, make sure that the Fedora 24 software you are using is up to date and that you have a backup of your most important files and settings.
You will then need to install the DNF Upgrade plugin using the first command listed below. After installation, you can start upgrading with the second command.
sudo dnf install dnf-plugin-system-upgrade sudo dnf system-upgrade download --releasever = 25
When all the packages are down, you have to restart your system, no matter what method you used. Upgrading the system will continue and it will take a few minutes to complete. If you experience any problems, you can ask for help Fedora community or the wiki page of the project, referring to the paragraph ” DNF system upgrade. "
