Migrating 170 to new i5 520

["Bob Cagle" <bcagle@xxxxxxxxxxx>]

I am reading over the instructions in Appendix D of the Backup &
Recovery guide, and I'm curious about one thing:

Why would I want to _replace_ the OS on the new 520 whenever it is
already installed and running???  What is the reasoning behind this and
why can't I just move over my User Libraries, Security, and
Configuration data with just simple Save/Restores?  

The manual doesn't explain this, at least not that I have found...

Can anyone give me a good reason?  We are a very small shop, and if I
had to, I could just recreate the user profiles and devices on the new
520 manually.
