No. I'm saying if the migration fails the database will be left in an
intermediate (and likely incorrect) state.

South *works* with mysql. But because of *mysql's limitations* if there
is a problem while South is *modifying the database schema* (the DDL) it
has no way to *rollback the changes*.

That's what it tells you: if there is a a problem during the migration
(because there's a bug in your migration), south *can not* put the
database back in the state it was before you started the migration
because mysql *does not provide the tools to do so*.

It's not an incompatibility, it's mysql being a gigantic turd, no
migration tool can fix that no matter how much they polish it.
