How can I convert a Spotfire dxp file from version 6 to an older version, i.e. 5.5 ?
Please let me know if I should clarify anything regarding this question.
Spotfire is not backwards compatible. The only thing you can do is rebuild it.
Added: To avoid confusion around forward / backwards compatible. This means that you can open .dxp files saved with older versions of TIBCO Spotfire with newer versions, but you can not open files that are saved with a higher/newer version of Spotfire than that you are you are using.
