Ncopy is part of the Locally Enhanced Sampling (LES) code. It will not be in
the prmtop files for normal runs and so should always be zero. It will not,
therefore have affected the results. If you are not using sander.LES you can
safely ignore it.

What is the difference you observe between amber 7 and amber 8? If you can
post some examples I can let you know whether the differences are important
or not.

Also, make sure the test cases pass for your current amber installation.

All the best
