Outlook 2003 Lost Notes

I recently upgraded from a Windows XP laptop to a Windows 7 laptop.  Copied all my files and folders over and created my Exchange email account on the new unit.  All my Emails, Contacts and Calendar entries came over fine but I lost my Notes.  I also copied both my .pst and .ost files but maybe I put them in the wrong directory.  Can you tell me what I need to do to recover all my Notes from my Outlook to the new laptop?  I had some very valuable information on them and really would hate to lose them.  The old laptop drive is still intact and I can download from it at any time.
Thanks,
