Upgrading from a previous Fedora

One of the great new features is to be able to do a live upgrade from an
older Fedora release to Fedora 11. You simply have to install the new p
ackage called preupgrade and run the program as root:

# yum -y install preupgrade
# preupgrade

Code :
[root@localhost ~]# yum -y install preupgrade
Loaded plugins: refresh-packagekit

This process does take a LONG TIME, requires a high speed internet connection
and has a couple minor gotchas but so far I've done a couple upgrades with no
data loss and pretty much everything has "just worked" afterwards. You don't
need to download and burn any ISOs as the upgrade is done on top of your current
installation.

Available Fedora Releases :

* Fedora 11 (Leonias)
* Fedora 10 (Cambridge)


The computer do :
1. Download release info
2. Download installer images
3. Determine which packages to download
4. Download packages
5. Prepare and test upgrade

Total Volume : 1,6 GB

After the preupgrade script downloads a ton of packages it will reboot and begin
the upgrade procedure automatically. Follow the instructions and after the upgrade
is complete log back in and you'll have to fix a couple little things. One things
is that you'll need to update the Livna repository file below and then clear the
yum cache. Once you do that you'll have to do an update again and this time yum
will automatically update any extra software you had installed from Livna with
he previous version.

# rpm -Uhv http://rpm.livna.org/livna-release-9.rpm
# yum clean all
# yum -y update

This too will take a while since it's likely that dozens of packages will need to be updated. Once it's done it's a good idea to reboot again for good measure and if all goes well you should be done!
