Older MS formats are mailbox.pst and mailbox.pab for filenames. Outlook 2000 and newer combine the address book into the same file as the email, outlook.pst. Save this file and place it on the new machine, make sure it's not read-only, set up your account on the new machine and import from the backup file.
Outlook does not let you browse to the backup file anymore, as previous versions did. It defaults to a new file on the C: drive. So you have to Import your old messages. Newposter
