Red Hat does not support in-place upgrades between any major versions of
Red Hat Enterprise
Linux. A major version is denoted by a whole number version change. For
example, Red Hat
Enterprise Linux 5 and Red Hat Enterprise Linux 6 are both major versions
of Red Hat Enterprise
Linux.
In-place upgrades across major releases do not preserve all system
settings, services or custom
configurations. Consequently, Red Hat strongly recommends fresh
installations when upgrading
from one major version to another.
