Upgrading from RH8.0 to Fedora

Has anyone had experience in upgrading from Redhat 8.0 to Fedora?

I run a shared RH8.0 box with web server, mail etc, and someone took it upon thereselves to upgrade IMAP, which led down the slippery slope of RPM dependencies and eventually the server broke after glibc was updated.

The box is now back up and running, but a number of the services (particularly those that rely on openssl) are not working properly.  I've lost track of what has tried to be "fixed", but I think most of the updated RPM's used to update/break the box were Fedora RPM's.

Is it as simple as plonking the Fedora CD's in the drive and choosing the upgrade option?

I havent tried upgrading redhat 8.0 to fedora but the upgrade from rh 9.0 is pretty painless. It should work ok but I would backup any important data first.

Hi,

   Upgrade from rom RedHat 8.0 to Fedora is like upgrade from Win98 to WinXP, it will end up to fresh
re-installing Fedora.

   Most of the rpms for Fedora are not compatible with RedHat 8. If you use --nodeps or --force option to
enforce rpm upgrade, then it ends up to your situation now.

   glibc is very critical system library with a lot of packages depending on it. Please roll back to the original version
if you still want to use RedHat 8.

   For Fedora upgrade, please backup all the data and database and then do a fresh and clean installation of
Fedora. That way is much safer and clean.

Regards,

Wesly

Hi Wesly.

Obviously a fresh install would be the best, but at a minimum, I was wondering if I could choose an upgrade option and have the basic stuff like network, user accounts preserved.  I don't mind reconfiguring bind, apache, perl etc.

Hi,

   As my experience, I didn't see the "upgrade" option during Fedora installation from CD on a RedHat 8 box. (or fade out)

> have the basic stuff like network, user accounts preserved.
   You can copy /etc/passwd, /etc/passwd, /etc/resolv.conf, /etc/hosts to a floppy
or
# tar czf /etc.tgz /etc   ===> backup whole /etc as etc.tgz and copy out etc.tgz to tape or NFS server.
Then use
# ifconfig eth0   <=== write down IP, netmask, broadcast
# netstat -r      <=== write down default gateway

Then do a clean installation.

Regards,

Wesly

If you are careful, you can preserve the accounts (/etc/passwd), the passwords (/etc/shadow), and also /etc/group (and home directories) by copying them all to external media before blowing your system away.

I agree with the others; trying to "upgrade" to Fedora from RH8 may possibly get you into some trouble....   a "clean install" would be best.

OK, a fresh install it is.

I have a backup of everything important.  I did a similar process a couple of years ago when we moved from Mandrake to Redhat.
