Answer
This particular swap — replacing two existing linked views with one new consolidated view while keeping the layout intact — doesn't appear achievable through Set Datasource Location or similar built-in Crystal tooling; the old view links persist regardless. The practical workaround used successfully instead is to skip trying to swap views entirely and directly modify the already-linked existing view itself to add whatever new condition/logic you needed the new consolidated view for, rather than trying to introduce and switch to a brand-new view.
