How do you propose they find that other documentation set if upgrading
from 9.6 to version 16?  Do we put the old docs somewhere on our web
site?  Do we have them download a tarball and unpack it?  How do we
handle old translated doc versions?  I realize the wiki isn't
translated, but if we have translators translate it, we should keep it

Uh, what exactly is this additional information you are talking about? 
Blogs?  Are you saying we have information about upgrades we have
captured but discard?

I suggest whatever we do, we place the information in a permanent
location that isn't moved or removed.
