Update prefix of an application and all its objects

Question

Suppose I have an existing application with prefix `ABC`. The application contains multiple objects, whose names start with `ABC_` according to Appian's naming convention. 
 Suppose now that I want to edit the application's prefix to `ABC123`(for instance in Appian Designer, by clicking the 3-dot button next to the application name, and selecting properties). 
 Is there a way to automatically update the prefix of all application objects?

philippu0221 - there is no way to update automatically, you need to update them manually, if required

Not possible, you can change the prefix and it will be effective while you are creating the new object but not for existing objects. You should change the prefix manually for the existing objects.
