Failed to import MySQL tables

Duplicator / Cloner / Migrator looked like it was going to work. After failing to migrate my site using All-In-One WP Migration, and Duplicator, I had high hopes for this plugin. And, unlike the others that hung up during the import process, this plugin appeared to run to the very end.

Unfortunately, the log informed me that ALL of the MySQL tables failed to import, despite the connection test working. I’m not sure what the cause of this failure would be. The MySQL .SQL tables got transferred to the new site, placed in a /db sub-folder, but the actual database was empty.
