Scrubbing "Methodology Data" from an old P6 (i.e. Version 3.5) XER File

Is there a way to strip "Methodology Data" from an old P6 file (ie Version 3.5) so that it can be imported into Version 7 or Version 8? Already know the Notepad "Cheat" to get an old version into P6, just not sure about the "Methodology Data" part. The file is only to be used as a template, so data integrity is not terribly important.

Thanks,
