 **Hint** Change the parameters according to your configuration. The `fallback-language` parameter defines the default language to be used for a multi-lingual vocabulary field for which no default language could be derived. The `continue-on-error` option prevents the migration tool to stop on data migration errors. These errors can occur if the data could not be inserted into the new vocabulary server. Possible reasons might be:
 - The vocabulary record is empty.
 - The vocabulary record contains data that is incompatible with some type restrictions.
