Upgrading Fedora EOL To Fedora 29

Is it possible to upgrade Fedora End-of-Life (EOL) version to a latest release version? Short answer, yes.

Fedora allows upgrades to 2 versions up. Not possible to instantly upgrade from legacy > latest. A longer waiting period is required. If you have all the time to kill, opt-in for this method. Else, you should make a backup of the current system (or files that you need), download the image file and boot it onto a flash drive and install it the traditional way.

Real life situation: We have a 64-bit Fedora 25 workstation that needs to be upgraded. In this case, we will need to upgrade to Fedora 27, only then proceed to upgrade to Fedora 29.
