In Oracle, as sooin as a user is created, a schema is being created for that user. Users that have no schema objects on their own or only have schema definitions filled with synonyms are being migrated as empty database definitions to MySQL.

Currently, empty schema definitions must be deleted manually and recreated as user definitions instead.

How to repeat:
Create a user, do not create any schema objects for that user.

See how the user is shown as a schema available for migration. Migrate it.

Watch MTK generating an empty database.

Suggested fix:
Annotate this condition in a migration, or do not migrate that database.

Additionally, think about a way to migrate a grant structure, which is currently not done.

Many thanks for writing a bug report. We are on the way to implement full functionality of MySQL Migration Tool into MySQL Workbench. We won't add this feature request anymore.
