CentOS - Jun 2017 - Updating to CentOS 7.3

I have remote systems that need updating. C5 and C6 systems.

Is there a "method" that is out there that you can load an ISO of 7.3
on a
different partition (other than root) tell the boot up process that the ISO
is there, do a clean install, install everything, auto reboot, and now C7
is installed and running.

Some configuring will be required after - but that is fine. The OS will be
updated.

Has anyone worked out something like that ?

I'm shocked after all these years Redhat does not have a good upgrade path
from version to version.

Thanks

Jerry

I do this all the time, but it never is to ?upgrade? a system, but to start a
kickstart.  All our configuration is in CM so its easier to just kick off an
install than to try to upgrade a system from el6 to el7.  Too many changes. 
I?ve created kickstarts that preserved a volume that had data on it, but wipe
the OS disks.
