In short, yes. Is your app written in Python? Let's say you have an existing model that is defined like this:
class Thing(db.Model): name = db.StringProperty() Now you want to add a "nickname" property. All you have to do is change your model to look like this: class Thing(db.Model): name = db.StringProperty() nickname = db.StringProperty() # the new property And you're done! From now on, all new entities will have this new properties. Your existing entities will not have that value however, so you'll have to be a little careful. As the previous message said, if you query for entities by using the new "nickname" property, any old entities that you haven't converted won't come back.
