Migrating from AS3 to AS4 - experiences w/ upgrade vs. reinstall?

[Russell Harrison]

I think its safe to say Red Hat wouldn't support a machine that was upgraded
from RHEL3 to RHEL4.  I know some people that have done this and from the
problems they encountered . . . its probably faster to just back up the
machine and reinstall everything from scratch.  Besides, I personally don't
trust upgrading across major kernel revisions.  It just seems like something
would almost have to go wrong.
