First thing I come across in the transition myself arrow1 the Skydome causes a Iray render to go black. Delete it and use the built in skydome that is found as a button on your render settings panel. By using the Daz dome you block out the light emitters as it is a solid object. There is also the Iray Sundial in your content library. The Iray dome can be altered with a HDRI maps
