1. Create a new community testme
2. create a few pieces of web content - content ABC and content DEF
3. enable staging (I selected just web content and web content display)
4. If I look staging has 2 pieces of web content, production has 2 pieces
5. Do a publish to live on an empty page
6. Using a database navigator, navigate to journalarticle table.
Result: New versions of all the web content are created, effectively doubling the data.
