Appreciate your replay. Could that slow down my machine or cause problems as I read it might? Would I be safer just going to Sierra? Thanks.

macOS High Sierra shouldn't create any problems, including system performance issues. However, you should create a Time Machine backup, so you can revert if necessary.
