I've tried something else - to upgrade from CentOS 5 to Fedora 7 and its
not easy but doable. Due to errors on my side I had to downgrade back to
CentOS 5 and back to Fedora several times to I think it can be done in
either direction.

The upgrade was live, I wouldn't recommend using the install disk for
the upgrade (mostly as the install disk won't recognize your current OS
and won't offer an upgrade - as you've probably noticed).

The main problem I has was with stuff that depends on the python ABI -
which is 2.4 for CentOS and 2.5 for Fedora 7. I don't think you'll have
the same problem with FC6 as I think both use the same python ABI.

I agree that CentOS is usually not good for home. (I use it as home server, 
but run debian-unstable VMs inside :) )
Still, many RPMs are available through the amazing DAG repository:
http://dag.wieers.com/rpm/packages/

Also there is the new EPEL project, but it's 'limping' a little..

CentOS is based on RHEL, not Fedora. SO you cannot upgrade from one to
the other.

I use the EPEL repository (highly recommended) and also the RPMforge
(http://rpmforge.net/) maintained by Dag. When I researched the LVM for
Centos5 issue, I found that Dag had about 40% of the libraries needed,
but still there was a lot of work to do to compile LVM for Centos5.

Think twice before you go the Centos way.

I use both FC (now Fedora without `Core') and Centos in the office.
Both work fine and I don't update the production machines (there is
no access from the Internet except for mail and ssh).

I installed Centos 5 on my home server and I update it frequently.
But Centos 5 is not for home use - its distribution does not have
media programs (like LVM, I wanted it for media streaming). So for
home/media use, may be Fedora (now 8) is better for your needs (few
RPMs are available for Centos on ATRPMS, FreshRPMS does not support
RHEL/Centos at all).

Ehud.

BTW. If you go the Centos way, start with Centos 5.1.

AFAIK You cannot cross-upgrade between Fedora and RHEL/CentOS.
You'll have to do a fresh installation.
(Which IMHO, is the best option to begin with)

upgrade to Centos 5 question

[Hetz Ben Hamo]

Hi,

It's always "fun" to play with a distribution that on one side has the
latest tech, but on the other side, ditches you on the side after few
months (and only giving you choice to upgrade, or be left without
updates)

I'm using Fedora Core 6 on my main web server, and today I found out
that the security updates are no longer available for Fedora Core 6.
Worse: ATRPMS, FreshRPMS are no longer maintained for FC6 which means
that if I want the latest security stuff, I need to roll my own RPMS
or fix things manually..

So I decided I want to "upgrade" from FC6 to Centos 5. I was wondering
if anyone did it and if so, what method? what are the "gotchas" that I
need to be careful of, or is it simply better to keep my data out,
format the machine and install centos 5 from scratch? (Centos 5 does
not recognize Fedora stuff, so the "upgrade" option is not given).

Thanks,
Hetz
