How to easily replace an over stove exhaust?

I have an over-stove exhaust with 2 blower drums that spin & 2 lights,on either side,it’s inserted/mounted up inside the custom oak cabinets,& to a duct that carries smoke,Cooking odors etc., outside. The unit is old & greasy & at least 30 yrs old,it works but I would like to replace it,but do not want to get in to ripping out the overhead cabinet.has anyone ever replaced one, by simply removing the metal system enclosed unit and inserting a new unit? Seems as long as I can find the same dimension exhaust that it could be replaced without much disassembly of any cabinetry
