Use the module Node Convert to change the content type of nodes

Frequently it might happen, that you want to convert the content type of a node or of many nodes. The Node Convert module is an easy way to do so. The options are straightforward: 1. To what content type should the node(s) be converted to and 2. Into which fields should the existing fields be inserted to (if you have the same fields, they will be selected by default, so that you only have to press "Convert"). You can also bulk convert many nodes of the same type to another one. To do so go to Administer → Content → Convert Nodes.
