To Upgrade the Repository

Upgrade the server repository either by using Internet or do it manually using CentOS 7 installation DVD.

To upgrade it via internet, go to the CentOS download mirror and choose any link.

CentOS

Now choose your Version. In my case its Version 7.

applications

Open the OS directory, choose the required architecture and copy the link to download to the newly created directory inside the server.

mirror list firefox web

Now use the rsync command to transfer the contents to newly created directory inside the server.
