Change the top of the cylinder

Hello,

I have a cylinder and between (0,0,0) (1,1,1) I want to just change the top location from (1,1,1) to (2,2,2)

How to do this in the code?

Create an empty game object at (0, 0, 0) and move the cylinder as a child of this empty game object. Now set the scale of the parent game object to (2, 2, 2).
