Will I lose Google Rankings if I build a new website on the 7.1 builder?

I built my website on the 7.0 builder, and would very much like to utilize the 7.1 builder as there's more features that I'd really like to use on it. However, I do not want to lose my search ranking if I switch. Does anyone know if this will affect my search results if I build a whole new website on 7.1 and switch my domain over? All the URLs would be the same, just on a different web builder.
