I'm curious what Redhat documentation says that? Here's a link to some RHEL5 documentation regarding upgrade: http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Installation_Guide/ch-upgrade-x86.html The first line: While upgrading from Red Hat Enterprise Linux version 4 Update 4 is supported, you are more likely to have a consistent experience by backing up your data and then installing this release of Red Hat Enterprise Linux 5.3 over your previous Red Hat Enterprise Linux installation. So what they're saying is that a clean install will give you the best possible/cleanest experience. That's a true statement pretty much no matter the OS, but upgrading is supported. Obviously they can't be 100% sure that you might have a setup which, someway, somehow, breaks anaconda from being able to complete an upgrade, as there are infinite number of combinations of hardware, but they test it and it generally works and is supported.
