NB Oktoberfest - question about secondary

Oktoberfest has been fermenting at 50 degrees for past 3 weeks........just about to target gravity so was going do a diacetyl rest for couple days then transfer to corney and sit at 32-33 degrees for next 2 months. Typically when I go to secondary I use a carboy with airlock attached.......this is my first time using corney for secondary and first larger as well. Can I Just seal the corney for the 2 months or do I need to modify lid to attach airlock?

You can just seal it up. Bleed off the oxygen with your pressure relief after you transfer and lager that bad boy.
