You would want to look at default traceflags and other options also which can be done at the operating system level.
I would recommend getting a trial version of Aireforge (https://www.aireforge.com/) and running that against your old and new server to check all the settings both from the OS and Serverside are the same.
One major thing to note is that if you are moving from SQL2012 to 2014 or above is the new cardinality estimator. If performance is your major concern I would leave your database in 110 compatibility level, enable query store, let it go for a few weeks then if your are required to update the compatibility level switch it to 130 and track regressed queries.
The new CE can make things faster, remain the same or drastically hinder performance for SOME queries
