Hi, is possible to stop the account being created for 'Guest' with the two entries in the address book, here's what's up. I have an existing store with One Page Checkout installed and the Guest entry is already in the customers table. To upgrade I have a test site with the latest 2.1.0 on the responsive_classic template with One Page Checkout installed. When I empty the customers table, customers info table and address_book table from the test site, then import the tables from the existing active store with the Guest account info in all three tables it creates a new Guest account leaving two Guest accounts, 4 entries in the address book and 2 in the customer info tables having all the same data, except the user id of course. Should I delete the old entry in all three tables so I don't have a conflict later in life, not worry? Thanks
