Unfortunately, the data is not portable between these versions. The
only thing you could do to preserve your webdb is to dump it into a
text file, and then inject into a 0.8 crawldb. As for the segments,
you will have to refetch them.
Is it just that no migration utility has been written? Is there something
about the structures in 0.8 that make migrating the data impossible,
or extremely difficult?
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.
