As I mentioned, you can use an archive table, or you could have a column
in the order table that references the sale_to or ship_to address id.
There are actually many different ways to do this. For example:
insert a new address, and update the users table to the new address_id.
The new address has a column called active(boolean). Thus all your sales
orders would reference an inactive, but valid address for that sale.
