To prepare crust, place wafers in a food processor; pulse 2 to 3 times or until finely ground. Add butter; pulse 10 times or until mixture resembles coarse meal. Firmly press mixture into bottom of a 9-inch springform pan coated with cooking spray. Bake at 400° for 10 minutes; cool on a wire rack.
Reduce oven temperature to 325°.
To prepare filling, beat cheeses with a mixer at high speed until smooth. Add the granulated sugar and next 8 ingredients (granulated sugar through vanilla), beating well. Add eggs, 1 at a time, beating well after each addition. Add pumpkin; beat well.
Pour cheese mixture into prepared crust; bake at 325° for 1 1/2 hours or until almost set. (Cheesecake is done when the center barely moves when pan is touched.) Remove cheesecake from oven; run a knife around outside edge. Cool to room temperature; cover and chill at least 8 hours.
