Recover Address Book after Snow Leopard Upgrade

Well at least I had a backup copy of my users directory.  The entire thing, not just the Documents folder.  So from my backup I copied over /backuplocation/username/Library/Application Support/AddressBook/AddressBook.data to Library/Application Support/AddressBook

Snow Leopard’s default Address Book file name is now AddressBook-v22.abcddb so I make a copy of that and then renamed the AddressBook.data file to AddressBook-v22.abcddb

Viola!
