How to Upgrade to Fedora 21 from Fedora 20
The best way to upgrade to Fedora 21 from Fedora 20 is to use the “fedup” tool to run the upgrade process. First we must install the “fedup” package, to do this, run:
$ sudo yum install fedup
Now, there are 3 ways to do the upgrade:
Upgrade to Fedora 21 using Network
This is easiest way to upgrade to Fedora 21, just run the commands and wait the packages to be upgraded, run this command to check for a new release.
$ sudo yum update fedup fedora-release
Now in order to start the upgrade process, run the following command.
$ sudo fedup --network 21 –product=workstation
The above command will upgrade your Fedora 20 system to Fedora Workstation 21, if you want to upgrade to the server or cloud version, you may
replace “workstation” with the name of the release you want, like:
$ sudo fedup --network 21 –product=server
And wait the upgrade process to complete.
Upgrade to Fedora 21 using the .ISO File
This way is good if you already have the .ISO file for Fedora 21, you’ll be happy to know that the “fedup” tool supports upgrading to Fedora 21 using its .iso file instead of starting a clean installation.
Let’s say that the Fedora 21 .ISO file is located in /home/user/Fedora-21.iso, you’ll have to run this simple command only.
$ sudo fedup --iso /home/user/Fedora-21.iso
And wait it to complete.. Don’t forget to replace /home/user/Fedora-21.iso with the path to the .ISO file that you downloaded for Fedora 21.
Note: The .ISO file must be in the same architecture of the installed system (if your installed system is a 32-bit system, you should download Fedora 21 32-bit version).
Upgrade to Fedora 21 using Another Device
This option isn’t very common in fact, but it may help you to complete the upgrade process anyway. Imagine that you have mounted the Fedora 21 source
to /mnt/ourfedora21 and that you want to upgrade your current Fedora 20 installation to 21 using that mounted device, you can simply do it by running.
$ sudo fedup --device /mnt/ourfedora21 --debuglog=debug.log
Don’t forget to replace /mnt/ourfedora21 with your mounted device path, if any errors occurred, you may check the “debug.log” file.
Now after you complete anyone of the steps above.. You still have to do one thing: After the upgrade finishes, reboot the computer, in the GRUB menu, you’ll see an option like this.
Select it in order to complete the upgrade.
And that’s it! You can now reboot to your new Fedora 21 installation.
