class Field in Drupal 9

Drupal 7 field source from database.

If the Drupal 7 Title module is enabled, the fields it provides are not migrated. The values of those fields will be migrated to the base fields they were replacing.

For available configuration keys, refer to the parent classes:

Plugin annotation

@MigrateSource(
  id = "d7_field",
  source_module = "field_sql_storage"
)
