Is there any way to convert Adobe Forms to Smart Forms?

Hi SAP Gurus,

In my project there is a requirement where we have to convert existing custom Adobe forms into Smartforms. I have searched in the SCN forum and found a thread http://scn.sap.com/thread/1485765 but it didnt fulfill my requirement. I have also tried with downloading of Adobe form in XML format and uploading the same XML file in the Smartforms transaction code but it thorws an error message "Invalid file format".

Any suggestions or solutions will be highly appreciated.

Thanks in advance.
