Comment (by kovshenin):

 No need to drop the `domain` index as it doesn't get created when the
 first part of the query fails. The side effect is that wp_signups doesn't
 get converted to utf8mb4 with a "Specified key was too long" error. From
 what I can see this doesn't affect updates on other tables.
