Red Hat would like to correct inaccurate information in the
Red Hat
Enterprise Linux 5.2 Beta announcement and Release Notes
about supported
update functionality.
Red Hat does not support in-place upgrades between major
versions of Red
Hat Enterprise Linux. Although anaconda's
"upgrade" option will allow
users to perform an upgrade from earlier major versions of
Red Hat
Enterprise Linux (such as Enterprise Linux 4 to Enterprise
Linux 5),
there is no guarantee that the upgrade will result in a
working
configuration. In-place upgrades across major releases do
not preserve
all system settings, services, and custom configurations.
For this
reason, Red Hat strongly recommends that you perform a
fresh
installation rather than a system upgrade between major
versions.
However, Red Hat does support updates between the GA
releases of minor
versions of Red Hat Enterprise Linux 4 or Red Hat Enterprise
Linux 5.
Red Hat recommends that users updating from one minor
version of Red Hat
Enterprise Linux 5 (such as 5.0 or 5.1) to Red Hat
Enterprise Linux 5.2
do so from Red Hat Network using the hosted Web user
interface, Red Hat
Network Satellite, the local graphical Updater, or the yum
command
line.
Even if no network connectivity is available, an update can
still be
performed offline using anaconda's "upgrade"
functionality. Note that
anaconda has limited abilities to handle issues such as
dependencies on
additional repositories or third-party applications. And,
unlike yum,
anaconda reports installation errors in a log file instead
of
interactively. Because of these limitations, Red Hat advises
customers
to test and verify offline updates using the exact
configuration before
applying the update to the actual target environment, and to
carefully
review the update log for errors after applying the update.
Finally, please note that Red Hat does not support system
upgrades from
the beta release to the GA product.
Sincerely,
the Red Hat Enterprise Linux team.
