ALTER TABLE log2 TYPE=INNODB;
But that's just theoretical. Also, some auto_increment columns need to be changed, et cetera. How did LJ do this? Is there a script somewhere that automatically does this change? bin/upgrading/update-db.pl doesn't notice the changes and doesn't suggest that I do anything, and I don't want to end up losing lots of data in this process.
Also, I propose that large changes like this go into this community to keep people aware of things like this. It would have saved me a lot of time and effort. Thanks.
