[...] a messier instances after it is done. The next step for the upgrade path is to do what I outline in upgrading from Fedora 10 to Fedora 11 and upgrading from Fedora 11 to Fedora 12. Here are the commands all in one place to make it [...]

By the way… if you want to:

yum update
yum clean all
yum clean all
yum update

rpm -Uvh http://mirrors.usc.edu/pub/linux/distributions/fedora/linux/releases/11/Fedora/i386/os/Packages/fedora-release-11-1.noarch.rpm http://mirrors.usc.edu/pub/linux/distributions/fedora/linux/releases/11/Fedora/i386/os/Packages/fedora-release-notes-11.0.0-2.fc11.noarch.rpm

yum -y update

Should get you going. I ran into a problem with Nessus (which I removed and reinstalled after) and MySql (which I removed and reinstalled after). Everything else built just fine.

Indeed! Keep writing the Yum upgrade docs, but only if you are doing it :) Obviously we can take previous FC>FC Yum posts and apply a bit of logic to do it on our own.

The benefit that I have had from your site, since FC5, is that you went through the pain and legwork that made me comfortable to do it in production.

Thanks for years of great help with Yum updates.

PreUpgrade works great when your upgrading from a relatively new Fedora install. Systems which started on Fedora prior FC5 made a very small /boot partition by default (only 30MB).

For these systems Anaconda or Yum is the only way, unless you re-size your /boot partition.

Same issue here as Cliff and Aaron – updating via yum still is really the only safe way to do this on a headless server. I've had about a 50% success rate using preupgrade – and 50% is clearly nowhere near good enough when you don't have access to your server. One of my machines uses eth0 for the internal IP and eth1 for the external – but preugrade assigns the IP address to eth0. Furthermore, when it does work, it requires taking your server offline for approximately 2 hours (at least it did for me) – on a production server, using yum, your server is only offline long enough to reboot it.

So, it's still not automatic enough to use preugrade unless you're using a Fedora desktop system.

Hmm, I just tried this and it failed badly. After rebooting, the machine failed to come back. A visit to the data centre showed that it was sitting with a prompt asking which Ethernet interface to use. I didn't actually care!

After hitting return, it ran for a while an then came up with an error message again requiring console access. The only option was reboot and I could envisage myself getting into an infinite loop. However, after the reboot the machine came back into Fedora 10 and I breathed a sigh of relief, relocked the cabinet and went home.

Can we please go back to your old way of doing it? Besides the obvious advantage that it actually works, it also minimises downtime and works remotely. Please don't stop writing the guides that use yum; I miss being able to come here, copy and paste two lines of code and have my machines upgraded, as I have been doing since FC7.

Thanks,
Cliff.

It appears that the above will only work if you are obtaining an IP address via DHCP. A little googling seems to indicate that if you want to use preupgrade-cli with a static IP it must be listed in the command line. (Apparently all of the /etc/syconfig/network-scripts files are completely ignored when upgrading.) This is a bit frustrating since it is a significant departure from the behavior when upgrading with yum.

Install PreUpgrade with:

yum install preupgrade
