There is a bus that will take you to terminal 6 but it may be easier and faster to just walk. I will let others chime in on that.
Walking will require that you leave security and reclear at Terminal 6; the bus is airside. I have not taken the T4-T6 bus, so I don't know how long it takes. It must be quicker than the old T4-T3 bus as T4 and T6 are on the same side of the airport.
