Pagemaker 6.5 file Conversion

i've read the older posts concerning this matter and have found, quite frankly zero help from ADOBE in this matter, when they should be the ones who should be spearheading this charge.  they are the ones who have created this issue with the newer version incampatibility and should also be the ones who should fix the mess.  why can we not get a better situation where we can convert older outdated files types to newer versions of adobe products?  i have a LARGE pagemaker 6.5 file that is incredibly importmant to me.  it contains thousands of hours of work in it.  i've been hanging on by threads with a less than decent PDF it made 10 years ago.  i've decided to go back to the original PM6.5 file and revamp it.  I purchased a copy of Illustrator hoping i could just open the PM6.5 file and convert it, only to now read that i am many versions outdated.  there doesn't seem to be any third party out there creating conversion programs that will convert 300 MB 300 page PM6.5 files online or otherwise.  ADOBE what is your opinion on this matter?  i see nothing from you.  Why is there no conversion method available to graphics professionals and individuals?  Are we just left for fodder?  Thank you.
