I'd leave it to ferment at 62 until it slows down, then let the temp free-rise to about 70ish for a d-rest and to maximize attenuation. Give it 10-14 days before lagering it for 2-6 weeks, depending on how patient your are.
Note: I only have experience with pale German beers brewed this way - this yeast and procedure might not work well at all for dark lagers and beers from other parts of the world.
