Hamilton will definitely need to work harder than before. Because while Mercedes had different cars each year, and it took time to adjust to them all the time, Ferrari is a whole another team together. Obviously Hamilton isn't new to change, just a few years ago, Mercedes had a car that literally jumped up and down all the time, ruining the back of the drivers, I am sure that was even worse than driving Ferrari for the first time.

But the problem is that it's a brand new team, so he will get to drive a lot more to get used to it first. Plus, it is not just the car, the team staff is different too, no more Bono, no more Toto, there is nothing going same for him, he will need to get used to every staff member there instead.
