Last night I thought of upgrading my Fedora 11 to Fedora 12.I went through Fedora Official website and came across a new tool called preupgrade.It went fine and so wanted to share it with you all.
Here we go...
In most cases, the simplest way to upgrade an existing Fedora installation is with the preupgrade tool. When a new version of Fedora is available, preupgrade downloads the packages necessary to upgrade your installation, and initiates the upgrade process.
Install preupgrade with your graphical package manager, or
type yum install preupgrade at the command line and press Enter.
To run preupgrade, type preupgrade at the command line and press Enter.
Note:
If the contents of your /etc/fedora-release file have been changed from the default, your Fedora installation may not be found when attempting an upgrade to Fedora 12.
You can relax some of the checks against this file by booting with the following boot command:
linux upgradeany
Use the linux upgradeany command if your Fedora installation was not given as an option to upgrade.
To perform an upgrade, select Perform an upgrade of an existing installation. Click Next when you are ready to begin your upgrade.
To re-install your system, select Perform a new Fedora installation and refer to Chapter 6, Installing on Intel® and AMD Systems for further instructions.
