...this was always the case though, even when upgrading H3 versions.  
Configuration options have been added/changed during the H3 line from  
time to time, causing the need to re-evaluate the current configuration.

Not to mention that H4 has a boat load of new features, and it would  
be benificial to a sysadmin to familiarize him/herself with the new  
configuration - something that configuring a new H4 install will  
provide.
