Prepare servers • HW/SW reqs! • Install Share. Point • Add servers to farm • Start Search Service Instance • Create SSA Create a new topology object for the SSA Add search components to the topology Assign components to servers Activate the new topology This will replace the single-server topology with a scaled-out topology
