Export Visual build application from one Dev instance to another

Summary:

We are trying to export and import visual builder application from one VB instance to another. On import to the new VB instance we also want to point to different ATP DB / Schema.

We have developed the VB app in our organization 's instance and want to move it to different client instances. But when we export/import the VB application's ATP schema for BOs is hardcoded in the imported app , please advise how can we change the ATP DB schema reference in the imported application.
