Well, it sure won't hurt anything to lag the new ledger (by the way,
there are better options to the old fashioned hex head lags--Home
Depot sells a lag that drives with a power drill, and there are also
ledgerlocks, for example). However, if the deck below is fastened to
the house, and the deck above is fastened to the deck below, you
should be OK. By the way, are you pulling a permit for this? If so,
your city building department will have something to say.
