Upgrad from CentOS 5.x to CentOS 5.9

If you are already running earlier version of CentOS 5.8 or any other older 5.x version. You can easily upgrade your system by simply running “yum update” command from the terminal. First check out the currently running version of CentOS you are running.

[root@tecmint ~]# cat /etc/redhat-release

CentOS release 5.6 (Final)

If your are using CentOS 5.x version, you can easily upgrade to CentOS 5.9. The upgrade process is very simple all it needed is to run “yum update” command.

But before upgrading, I recommend you all to list down all the packages with ‘yum list updates‘ command. So, you would get the better idea which packages are going to install.

[root@tecmint ~]# yum list updates

The only official way to upgrade any CentOS 5.x to CentOS 5.9 using. (Important: Please take backup of all important data).

[root@tecmint ~]# yum update

Once upgrade process completes successfully, check version again by running the command.

[root@tecmint ~]# cat /etc/redhat-release

CentOS release 5.9 (Final)
