I have different content types (5) migrated from my D7 site, which I want to unite into one content type, because they have the exact same fields.
- Proceedings - Refereed
- Proceedings - Unrefereed
- conference proceedings
- conference proceedings (unrefereed)
Now I have made a general content type publication.
Is there a way changing the content type of existing nodes or do I have to build the nodes (add content) with the new Content type again (talking about ~ 95 nodes)?
