YAMLForm Migrate

This module provides a migration source plugin and a migration template to migrate Drupal 6 webforms to Drupal 8 YAML Forms. It should be installed in the normal way before the D6 to D8 migration is built.

The migration reads the webform tables in the D6 install and creates YAML forms by converting each webform component into its YAML component.

As part of the this migration the webform source plugin will attempt to add a YAML form reference field to the webform content type and attach each migrated YAML form to the relevant webform node.
