Smartest way from A to B
Assuming all adequate precautions, clones, backups, etc. and acknowledging that (with enough time and patience) the "best" way to upgrade from 10.5 to 10.6 would be a clean install, fresh user account (with same name, etc.), fresh install of all apps, and selective copying over of data from the clone, my question is, is there a net difference between:
a) Running the standard 10.6 "upgrade" Install in place
b) Erase & Install followed by Time Machine restore or Migration from a clone of 10.5
c) Any other combination, i.e. E&I followed by Migration of only User and Documents + fresh Application installs, etc.
In short, what's the sanest way from 10.5 to 10.6 with all Users, Applications and settings intact?
