[PLUG] CentOS 6.x to CentOS 7.x

[Thomas Groman]

I highly discourage you from trying to upgrade major CentOS releases.
Something always goes wrong. It's also about that time to be upgrading
everything from scratch when RHEL/CentOS release cycles end. There is
more than just packages needing to be upgraded. the whole system is
different. For example; CentOS 6 uses SysV INIT while CentOS 7 uses
SystemD INIT with compatibility symbolic links for legacy INIT only
programs. Trust me it is more difficult and time consuming to upgrade a
CentOS6 box to CentOS 7 than to just start a new CentOS 7 box and
migrate your stuff over. You don't want be be running EOL software
especially in a production environment.
