Will the $30 upgrade all 5 Federal returns to Premier? Yes ... all returns completed with the Premier version will be the same.
But the real question is WHY do you need/want to upgrade the program. The CD Deluxe version can handle ALL tax forms and ALL tax situations just the same as the higher priced version. So unless you need extra guidance in the investment or rental section there is no reason to upgrade to a higher version. It is like buying a car ... the chevy and cadillac will both get you where you need to go but they simply look different.
