Feel surprised to find in the RHEL 5.3 release notes the following statement:
While anaconda's "upgrade" option will perform an upgrade from Red Hat Enterprise Linux 4.7 or 5.2 to Red Hat Enterprise Linux 5.3, there is no guarantee that the upgrade will preserve all of a system's settings, services, and custom configurations. For this reason, Red Hat recommends that you perform a fresh installation rather than an upgrade.
So they are advising to reinstall RHEL 5.3 even when you're running RHEL 5.2.
*speaking _for me / as me_, as always, etc.*
I don't see the above text in the release notes, but what I do see is the top section of:
https://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Release_No...
...which implies (to me) that the text you quoted is saying something like "although a 4.7 => 5.3 upgrade has the same UI as 5.2 => 5.3, you shouldn't expect it to work as well in all cases".
And, of course, that's all anaconda specific ... going 5.2 => 5.3 via. "yum update" is expected to just work.
I meant announcement, not release notes. See:
https://www.redhat.com/archives/rhelv5-announce/2009-January/msg00000.html
If "yum updated" is expected to work, the quoted paragraph is very bad worded. This is the kind of thing the Ubuntu people are using against RPM based distributions.
And how ill-informed it may be, it is better to avoid than to remedy.
