Thanks for the advise, SleePy, and thanks for the convertor, Jay. Following unpossible's comment about continuing the deletion of = 0 in all of the continuing errors in the upgrade, I almost have it all complete, but I come across an error I'm stumped.
Converting topics (part 2)... Unsuccessful!
This query:
UPDATE `weightle_smf`.smf_log_topics
SET ID_TOPIC = 1
WHERE tempID = 1090798235;
Caused the error:
Unknown column 'tempID' in 'where clause'
