Hey, these are just bits and bytes on the disk, so nothing is impossible ;)

Sure, given enough time and resources you could write a converter; all 
I'm saying is that it would take a lot of tedious and error-prone 
coding, so for all practical reasons it's better to dump/inject and 
re-fetch. Unless your segment data is so precious that you are willing 
to bear the price of writing a converter.
