I would also change its overall style, add more modules. I've never done this and I am afraid it will take too much time. Is there a way to do it without my shop being not open for too long?
I do really care about saving all the data from my v1.4 version.
I am not super technical person, but I will try to do my best.
If you change theme. Install clean, newest Prestashop version on i.e sub domain and migrate whole data from old -> new one.
