I suggest you begin by reading the release notes for CentOS 7, which are
at http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 -- here is an
excerpt:
For the first time, there is a supported upgrade path from CentOS-6 to
CentOS-7. This path is only supported from the latest version of
CentOS-6 (being 6.6 at the time of writing) to the latest version of
CentOS-7. For more information on the upgrade procedure please take a
look at this page. The tools needed for this functionality are still
being tested and will be released at a later time. If you can help
with the testing, please see this CentOS-Devel mailing list thread and
this wiki entry.
So, upgrade to 6.6 first, and then use the upgrade procedure from Red
Hat, if you're willing to help with testing.
Or install 7 from scratch, of course.
