Conversion of mpx files to mpp file format

It seems that the only possible mpx to mpp conversion is related to export or conversion between two types of Microsoft Project files, something that can most likely be only reliably done using the program itself and only with version 2000 and later due to the fact that the previous versions did not support modern formats.
