I believe - what's it called, preup? - exists. I'll also note that the
overwhelming opinion is DON'T USE IT.

One good reason: from one full release of an enterprise o/s to the next,
there are many major upgrades - packages goind from, say, 4 to 6, and the
odds are that will break your system, or what you run on it. This is one
reason that /home, and other locations for data are on separate partitions
- when you upgrade, you tell it install, custom install, format /boot and
/, and you won't lose anything.

Counter example: torque, a cluster software package that we use heavily,
in the middle of CentOS 6.6, which is from EPEL, *suddenly*, with no
warning, went from 2.5.x to 4.2, which broke all of our clustering, and
killed a number of large jobs. We had to downgrade (and that was, um,
interesting, since EPEL did not see fit to either name the new package
something like torque4, and didn't leave the old one around to allow an
easy downgrade. Fortunately, we have a local mirror.....

Now think of upgrading from 6 to 7, and having something like that hit you.

Can you please fix your clock on the computer where you write your list 
mails?

That's depressing !!
Reason I asked is because the centos7 release DVD does not
support my  NVIDIA Corporation G98M [Quadro NVS 160M] (rev a1)
card.
It is incredibly strange that it is supported by Centos 6.4
which installed from DVD without a hitch.
