Do I change one at a time by tipping the fridge from the side or can I tilt & support tipping from the front to change out both at the same time

Both can be done by tilting the refrigerator to the back. I would suggest having a 2-4 inch support at each front corner that the front end can rest on while replacing the rollers.
