A conversion script that converts legacy Standard shaders to Standard Surface shaders is available in the Arnold menu of MtoA.

Why does my Maya shader network not render with Arnold?

In Arnold 5 there are Closure shaders & attributes. It is possible to connect a RGBA shader to a Closure attribute, but it is impossible to connect a Closure Shader to a RGBA attribute. A simple example would be when trying to connect a surface shader to the emission attribute of another surface shader. Standard SurfaceStandard Hair and Standard Volume shaders output closures rather than colors. This makes it possible to mix shaders efficiently, using the shader_mix node to blend or add two shaders including all their light AOVs.
