10 minutes? That's awfully optimistic - or very fast NY-style walking!
You need to go down the elevator from the T8 AC, then either outdoors along the roadway or inside thru the maze to T9, then clear security (which, btw, is usually pleasantly short IMO), then up the ramp, down the escalator, under the taxiway, up the escalator and into the concourse itself -- before heading to your gate (which, with my luck, is usually at one end or the other of the concourse).
