As KenEasy suggests, you need to leave the Lager in primary fermentation for at least 1 week before you rack and consider cold conditioning (Lagering). When you ferment at low temps, the primary fermentation takes longer than normal to complete and you simply should not rush a lager.
Did you take any SG readings? If not, when you notice no action in the airlock for at least 48 hours, then you will generally be right to rack it and leave in secondary for another couple of weeks, but don't do this before the wort has had at least 7 days in primary at such low temps.
You also might want to consider dry hopping the lager when you rack it into secondary...
Cheers,
