Refer to The Lifecycle of a Form Type for information on when / how a form type is regenerated.
Once the form business object / UI maps / application services exist, any subsequent form type regeneration will retain the primary key, as well as most of the references associated with the generated objects - e.g. BO options, BO plug-ins, etc. Only the following updates would take place:
The existing BO's schema is replaced.
The existing UI maps' HTML is replaced.
If the parent form BO referenced on the form type has changed since the last generation:
The Parent BO and Maintenance Object references on the existing BO are replaced.
The access modes on the child application services are replaced.
