The only lwp to odt conversion that makes sense, would be a transformation of old Lotus Word Pro documents (.lwp) to documents based on the OpenDocument Format scheme, such as .odt files from OpenOfficer.org or LibreOffice Writer. You can achieve this for example with LibreOffice/OpenOffice by using the default File ► Save as.. function as these programs should still support old .lwp files.
