Oktoberfest still going

I transferred the Oktoberfest into the five gallon secondary. Unfortunately I had to throw away about a 1/4-1/3 of a gallon, because I had over five gallons in the primary. The beer tasted normal, but it definitely needs more time. It did not have a fruity ale taste, so it appears the fermentation was at a good temperature and it went ok. I was concerned when the yeast initially did not start. I have gradually lowered the fridge to the low 40's, after a fermentation around 55-57. The beer will continue to lager until the end of the month when I put it in a keg.
