In a search for potential signals of neutron (n) to mirror-neutron (n^{'}) oscillations, a collaboration centered at the Paul Scherrer Institute investigated the remaining parameter space claimed by anomalies with a dedicated high-sensitivity apparatus. An elaborate magnetic-field-mapping analysis and Monte Carlo simulation of the cumulative n-n^{'} oscillation probabilities along the neutron trajectories inside the storage vessel complemented the neutron data analysis. Magnetic fields were scanned in the range 5
