Upgrading NodeJs What to do with Newman

Hi. We recently installed Newman 4.5.6 on a number of Linux servers, which have NodeJs 8.9.3 installed. We are going to upgarde to NodeJs 10.15. Newman installed itself in the NodeJs 8.9.3 paths.

When upgrading to NodeJs 10.15, do I need to reinstall Newman or can I just copy the newman directories over and update the symbolic links?
