wondering if system settings remain the same during os upgrade

[Appleuser4life60077]

I have a early 2011 macbook pro with the suspected gpu issue. however i put a ssd in an old early 2009 white macbook and had apple install yosemite on it and installed the ssd in my pro and it is working perfect so far running the and chip. in system profiles looks like automatic graphics is disabled. if i upgrade to sierra again with the system setting stay the same or will i have to reset it?

I think it should hold the settings.

so as long as i leave everything set the way it is.... it should remain the same settings it is now?

Yes, I believe so. That worked for me going from Yosemite to El Capitan.
