When you first create an application, the Production environment is in the Pre-launch mode. When you are ready to publish the application, you should change it to the Production mode. In the Pre-launch mode, you can freely drag your files or database to the Production environment. In the Production mode, you cannot copy your files or database to the Production environment. This protects you from possibly destroying your live application by overwriting your Production files and databases.

You copy databases and files up to the Production environment only until you first launch your application. After that, you push code to Production, but you pull databases and files backwards from Production to the Staging and Development environments for testing and development.
