Hello Guyz

First of all, I'm new to Linux with basic SSH knowledge, so any additional help would be much appreciated.

I'm using a Linux VPS

==
cat /etc/redhat-release
CentOS release 5.10 (Final)
==

I know this is an outdated version. My VPS came with all necessary modules : PHP, exim, CSF, basically everything you need to run a webserver.

I've already deployed few websites like Prestashop, Magento and all working great. I need some basic guides on how can I update my centos to latest version **Without** affecting any of my current working website/system

I'm using cPanel/WHM

Thanks in advance

you can not " upgrade" CentOS 5.10 other than the normal update

to move to 6.5
you have to do a new clean install

CentOS 5.10 might be "old" but it is still supported for about 3 more years
centos 5.10 will hit "End of Life" on 31 March 2017
