Another hole saw trick to increase the size of a hole is to find the hole saw that matches the size of the existing hole and use that to drill a plug out of scrap wood. Fit the plug onto the pilot drill of the larger hole saw and use that as a pilot to center the larger one. Works like a champ keeping the saw centered.
