Convert Bundles
This module provides actions to convert entities from one bundle to another. You can convert individual entities, selected entities from the content administration page, or all entities of a specific bundle. It integrates with other Drupal modules like Rules and Views Bulk Operations.
This module adds drupal actions to convert entities from one bundle to another.
Content can be converted individually from a "Convert Bundle" tab on the node (or entity), selected nodes from the content administration page (/admin/content), or all entities of one bundle to another from the convert bundles config page (/admin/config/content/convert_bundles).
Since the convert bundles creates standard drupal actions for each type of entity, this module should work with other drupal modules such as rules and vbo.
