Hi,

I have CentOS 5.0 DVD and install on my system and running fine. I want to update it to CentOS 5.2 / CentOS 5.3. Can anyone please let me know how to upgrade running CentOS to latest version.

Any help would be greatly appreciated !

You just install the updates to rpm's you don't already have the latest version of, there is no "procedure" to it - It is still "RedHat 5". Generally a standard "yum update" will do this.

Thanks for the quick reply , i hope if i run yum update will help me in this.

Think of the sub-releases of rhel more like errata baselines. Install 5.0 and update 300 packages, install 5.4 and update 3... same end result.

someone can confirm that this solution works fine?

only "yum update" command is need?

if there's some dependencies problem, all instalation will broken???

thanks!

there is no difference between 5.0, 5.1, 5.2, 5.3 or 5.4 other than the patches and fixes released as RPM's. If you install redhat5.0 and run "yum update" it will become 5.4. you are *NOT* doing an upgrade.

just run " yum update" and you will have a cent 5.4 .

As a disclaimer to some extent though, some packages do change in subtle ways as succdessive updates are added, so specific customizations you make to packages can work slightly differently after an update, e.g. fixing a bug might make a security feature work when it didn't before unbeknownst to you. Always the way with updates, but there is no cast iron guarentee everything will work exactly as it did before, but such is IT and this shouldn't be seen as a drawback or such.

The scenario is:

- remote server w/out physical access
- production installation (firebird running, people working, etc)
- complicated, nervous and average crazy customer

so I'm doing this update through "back door" because I need it to run some X applications via ssh -Y

let's start:

yum groupinstall "X Window System"

shit!

it's logical trying soft method:

the same: search for this (is outdated) install (don't work: more conflicts) and so on...

I think never can update this system

after too many tries, I see the light: yum remove <some_packages> and yum update <concrete_packages>.x86_64 and finally Xorg runs!!

now fighting with Gnome etc etc

regards!
