Both are excellent machines but I wouldn't consider it an upgrade. Some would say you already have the better machine so, unless you particularly want electronic dose or two grinders stick with the M4.
The Mazzer definitely has a better and easier grind adjustment and the M4 a better doser. Ease of changing grinds all the time makes the MM the choice for me but my mate swears by his Macap.
If it's in good condition and cheap buy it anyway. You can never have too many grinders
