Upgrading from CentOS 6.x to CentOS 6.5
You can easily upgrade from any earlier CentOS 6.1, 6.2, 6.3 and 6.4 version to CentOS 6.5 using “yum update” command from the command-line. Before updating, check out existing version, if you are running any.
[root@tecmint ~]# cat /etc/redhat-release
CentOS release 6.4 (Final)
The upgrade process is much easier and straight forward, all you have to do is simple run the “yum update” command. But before heading-up for upgrade, I suggest you all to take backup of important files, databases, configuration files etc.
Next, run the ‘yum list updates‘ command to list down all the available list of updates. The update list gives better idea about what packages are going for updates.
[root@tecmint ~]# yum list updates
