upgrade mia_material

Open the attribute editor for your mia_material_x shader, open the "Upgrade Shader" section and then press the "Upgrade shader to mia_material_x_passes" button.

thanks! I know that! But, if i have many mia_material_x shader, i can't upgrade each shader!

Sorry, I did not understand.

There is a helper method written in MEL for upgrading multiple shaders to their pass equivalents. Check out $MAYA_LOCATION/scripts/others/upgradeAllMentalRayShaders.mel.

There are two methods of use:
upgradeAllMentalRayShadersOfType(string $oldType, string $newType, string $suffix)
and
upgradeAllMentalRayShaders(int $passSupport)

The first can upgrade ALL of the mia_material_x shaders in your scene to mia_material_x_passes by invoking it as follows:
upgradeAllMentalRayShadersOfType("mia_material_x", "mia_material_x_passes", "_passes");

The second can be called like:
upgradeAllMentalRayShaders(1);
and will upgrade ALL of the mental ray materials in your scene to their _x_passes equivalent if they exist (this includes mia_material, mi_metallic, mi_car_paint and misss_fast_shader).
