ok, so the conversion is not the problem, but the proofreading is? if that is the case then i'd suggest to make the conversion without proofreading but add a warning that these parts have not been proofread.
that way we are sure that the docs are at least available and won't get lost. with the warning, people will be more encuraged to report errors (as opposed to only be frustrated that things don't work as documented)
the proofreading can then happen over time as people ask questions about specific sections.
btw the old tutorial seems to be here: http://pike.ida.liu.se/development/cvs/browse.xml?dir=7.2/tutorial&modul... that directory is empty in 7.4
