InRoads Storm and Sanitary Files Compatible with OpenRoads?

We have a project that is starting in OpenRoads but some of the preliminary drainage design was already completed using InRoads Storm & Sanitary. Are the files and databases created using InRoads Storm & Sanitary translatable to OpenRoads? Or do I need to use the Subsurface Utilities toolbars to recreate my drainage networks and design in OpenRoads?
