I don't think there is a way to upgrade.
You will have to fresh install of 64 bit.

Hi Snowpine,
After restoring data on 64 bit Cent OS 5.8. While trying to start software. It is giving error.


Starting CGATE service: insmod: error inserting '
i810-tco.o': -1 Invalid module format

And there is no information about"i810-tco.o" on net.

I see that "Cyber Gatekeeper" is 3rd party commercial software (not provided/supported by CentOS) with a Support page on their website. Suggest to contact their tech support department for assistance how to install their software on 64-bit.

You are aware that CentOS 5.8 is not supported ? right ?

the only older 5 is CentOS 5.9
the old 5.8 repos have been moved to the archives " the vault"
none of the 5.8 repos listen in the 5.8 install will work

also if this is 32 bit hardware you can NOT install a 64 bit OS to it

for a 32 bit server
buy a 64 bit server
install CentOS 5.9 ( the current in the older 5 series , with 6.3 the current)
import the old data from the old server

Hi John, Actually the scenario is, I am in india and my customer is in Austrelia. Now there is a machine having 32 bit centos 5.4 installed on it. There in no internet connect on that server and there is no optical drive. That server is connected with another server, which have internet connection.I am accessing the server via SSH thru internet faced server. Now customer wants to upgrade 32 bit CentOS 5.4 system to 64 bit CentOS 5.8 system, without formatting(Why? I dont know. But customer is strictly saying to do not fresh install). I think now you understand why I am bind to upgrade. Please guide me

Your customer has requested an impossible task. In your situation, I would work together with the customer to understand their needs and recommend a better solution.

as per "snowpine's" post
the 5.8 repos are not there
here is a copy of the place holder README in the 5.8 mirrors
Quote:
This directory (and version of CentOS) is depreciated. For normal users,
you should use /5/ and not /5.8/ in your path. Please see this FAQ
concerning the CentOS release scheme:

http://www.centos.org/modules/smartfaq/faq.php?faqid=34

If you know what you are doing, and absolutely want to remain at the 5.8
level, go to http://vault.centos.org/ for packages. Please keep in mind that 5.8 no longer gets any updates

Hi Snowpine,
Sorry to say but it is not an impossible task. actually I have done it very very easily with this tutorial. I made some minnor changes in this tutorial and made working for me. here is the link: http://supportex.net/2011/06/install...dora-remotely/
First of all I copy the vmlinuz and initrd.img file from the ISO to /boot as vmlinuz_remote and initrd_remote.img in target server.
Then in grub.conf configuration, in method I put http://192.168.1.11/dvd (192.... is the local server and in dvd folder I copied the entire DVD of Cent OS 5.8)
On VNC you will get the screen of installtion, for where you can select UPGRADE to upgrade the server.

the "impossible " part is that 5.8 is DEAD
it will NEVER receive any security updates
NO security fixes
No bug fixes
and will be OPEN to every known and FIXED security threat

and with CentOS 5.9 the VERY LAST minor upgrade
that will still have 5 more YEARS OF SUPPORT

install CentOS5.9!!!!

John VV and snowpine:

Based on http://en.wikipedia.org/wiki/CentOS
It shows:
In accordance with the Red Hat Enterprise Linux Life Cycle CentOS 5 and 6 will also be supported for 10 years.[63] Previously, CentOS 4 had been supported for 7 years.[64]
End of support schedule CentOS Release Full Updates Maintenance Updates
3 2006-07-20 2010-10-31
4 2009-03-31 2012-02-29
5 Q1 2014 2017-03-31
6 Q2 2017 2020-11-30

And on http://wiki.centos.org/About, it shows:
CentOS is an Enterprise Linux distribution based on the sources from Red Hat Enterprise Linux. Starting with CentOS 5 each version is supported for 10 years (by means of security updates, previous versions for 7 years). A new CentOS version is released approximately every 2 years and each CentOS version is regularly updated (approximately every 6 months) to support newer hardware. This results in a secure, low-maintenance, reliable, predictable and reproducible environment.

Do I misinterpret messages shown in these URLs?
If not, why there is no security updates for 5.8 any more?
If yes, then when 5.10 is available next year, should 5.9 be put to sleep, like 5.8, and no more 'security update' after 2014?
Did Centos.ORG change their update policy recently?
Thanks

red hat is NOT centOS

yes cent is built on the RHEL source
BUT they ONLY support the current version only
when CentOS 6.4 came out all support for CentOS 6.3 ended

Now once cent6 hits 6.9 , that will have about 5 to 7 years of support -- being the last minor upgrade

it you NEED long term support for a minor version
install RHEL and buy the server license

so CentOS 5.9 will still get security and bug fix updates for years
but NOT 5.8

Basically, those Support Schedules you noted are for the major version nums, not minor ones (which is why they're not mentioned).
Here's the RH equiv page http://www.redhat.com/security/updates/errata/.

Does it mean CentOS 5.9 is the last version of CentOS 5 (never 5.10)?
Thanks
