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

[Tom Hansen]

We have RHEL AS3 Update 7 and are considering upgrading to the current 
RHEL AS4 to gain the additional hardware support of the 2.6 kernel.

We would like to do the upgrade rather than reinstalling everything from 
scratch.  Is this just an empty hope, or does this stand a reasonable 
chance of success?

Experiences, anyone?

Thanks.
