Convert Outlook Express Folders And Address Book To Outlook In Windows 7

I have over 13 years of Outlook Express folders and addresses that I desperately need to convert to Outlook 2007. I should have imported them into Outlook before I made the "Easy File Transfer" to the new Win 7 machine, but didn't know I needed to do that. Several years ago I had imported the files into Outlook, although that data did transfer it is now way out-of-date and full of duplicates.The up-to-date data is still in my old machine and also in an external hard drive backup. I have isolated the Outlook Express personal folders into .dbx format and the addresses into .wab format.Is there a way this can be reformatted into Outlook? Or is there some other way? I would probably also need to delete what is already in Outlook first, or I would have many more duplicates.
