Explanation: After migrating an app from QlikView to Qlik Sense, there may be some unconverted objects.
In this case, the data architect should re-create the unconverted objects in order to ensure that the app works properly in Qlik Sense. The other options will not work, as saving the unconverted objects as extensions or master items will not ensure that the app works properly, and removing set analysis statements will not help either.
