fedora to centos upgrade?

[Steve Holdoway]

Has anyone done this? I've got a remote server that I've just taken
over, and some idiot has built it on Fedora! Taking it out of production
is no problem, but access is difficult if anything goes wrong with the
upgrade.

I'll take all precautions I can think of - like a failover fed 7 kernel
for grub, but experiences of others would be gratefully received (:

Cheers,

Steve

Fedora tends towards bleeding edge, Red Hat, hence CentOS, is
conservative. So they will have a number of incompatabilities. I would be
_very_ wary of trying to "upgrade" from one to the other.

Absolutely. I'd like to shoot the 'admin' who installed a production
server on it. Maybe I should wait for CentOS 6 and hatch a cunning plan
in the meantime...

Hi Steve,
it is possible however depends what version of Fedora you are currently
running.
I'm guessing you are running Fedora 7?

The problem you have there is RHEL/Centos 5.5 is based on Fedora 6, so
effectively you won't be upgrading but downgrading. The latest RHEL 6 is
based on Fedora 12 so you will be able to update to that using YUM,
although you would probably need to go via fedora 8,9,10 and 11. You may
find this difficult though as I think 8 and 9 are now out of support.

Probably worth installing 7 on a spare box and trying it though.

Out of curiosity what is this box running, and what is your issue with
it running Fedora?

Cheers

Jon

A Fedora desktop OS has a support lifespan of 6 months, RHEL/CentOS is 5
years. I have no way of keeping this server secure as the patches aren't
( "officially" ) available.

This is the core of the problem - apache, ssh, php, clamav and many more
cannot be properly supported.

Sure it was great when installed - pretty toys and all. But that was
then, and now I'm completely stuffed without going back to the dark ages
of compiling from source - which really should not be necessary in this
day and age for a mainstream web server.

Yeah fair one!
might be worth pointing yum at centos 5.5 repositories including EPEL,
RPMForge and UtterRamblings to see what will actually be picked up for
update.

if you want me to send you the repo files for the above just shout.

I think I did it in the past using some post I found in the internet, it was
something like just setting the CentOS repositories, install some CentOS
"branding" packages , yum upgrade and pray. I don't think I have the stones
to do it in a production server though :( Sorry for being so vague, but
memory it's not my strong point
