Create Version Directories
You can create version directories on your server instance via the Business Manager if you have the appropriate permissions.
When developing your application in Studio, you can select which directory to upload files. Using version directories lets you retain previous versions while saving your changes to a specific server directory so that you can retest the application against an older version.
In Business Manager, define your directories and set one of them as active. In Studio, each time you create a project, define the upload directory.
