Converting a project to a Mongoose form
You can convert your App Builder project to be a Mongoose form. After converting the project to be a Mongoose form, however, you cannot reverse the process from Mongoose form back to App Builder project.
App Builder creates a Mongoose form that is, as
closely as possible, the Mongoose equivalent of the original App Builder project. You
can now open and use or modify the new form in Mongoose, using the same configuration
used by App Builder.
