In the past, before MoTs were computerised, you could take your car in for a test upto a month before old MoT expired and, if it failed, you could still drive on the basis that you could show the old certificate as still being valid. Would this still be the case? If your car failed now, say perhaps for something very trivial (like a wiper blade torn), would the DVLA database immediately show the car as having no valid MoT thus making you liable to be pulled over by an ANPR Police unit, or would you still be covered by the old certificate?
