The only supported upgrade is a CD-based upgrade, though I've heard courageous stories of in-place upgrades that have succeeded more or less.

Yes, I know that works well for Fedora, but we're talking about RHEL3 to RHEL4 here.... I'm much less convinced of this working.

In-place upgrades using Fedora are pretty smooth. I went from FC3 or 4 (don't remember which) to FC6 on a colo server in a PoP halfway around the world once.

There are a few gotchas when going from FC6 to FC7/FC8 though.

Interesting article about "pre-upgrade" (in-place upgrade feature) in RH Magazine recently:

About your link, maybe you cant remove it becuase it is being used by a program...? What error do you get when you try to remove it..? "access denied..?]]> http://www.dslreports.com/forum/remark,20468952 Mon, 12 May 2008 10:04:42 EDT RHEL Upgrade http://www.dslreports.com/forum/remark,20455402 joako : Is there any way I can do an upgrade of RHEL3 to 4 in-place on a running system? I'm having a hell of a time compliling kernel modules so I figured I might as well upgrade. I also created a circular symlink I can't delete!
