There should be minimal differences, but some defaults have changed,
which may impact results.

Thing to do is to run a short (say 20 step) MD simulation with Amber12,
and then with Amber18, setting ntpr=1 so that you can look for
differences. If the changes are not obvious, you could then post the
short examples to the list, to see if someone here can figure out what
is going on.
