That's the concept. The script in that post, if I recall correctly, assumes that you've already got the customer records loaded to the server, and just need to flip the unencrypted passwords into encrypted form so they can be used for real logins.

You'll have to load the database content manually yourself, and you'll have to communicate the customers' passwords to them separately on your own as well.

Loading the database involves 3 tables: address_book, customers, customers_info.
