Just a follow-up. DH is pretty clear about the upgrade instruction, if you install/upgrade from an earlier version:
[quote] 6 : Configuration

if you are upgrading from version 1.0.x, select ‘Load
Old Table Prefix: jos_
CHECK 'I have already uploaded the migration script to the server (e.g. via FTP/SCP)'
CHECK ‘This script is a Joomla! 1.0 migration script.’
click ‘Upload and Execute’
Otherwise, select 'Install Default Sample Data’
click ‘Install Sample Data’
Site Name: (the name of your site)
Your E-mail: (admin email)
Admin Password: (pick a password)
Confirm Admin Password: (re-type password again)
It won’t delete your existing site.
