Using SS2 DTM Feature names in an ORD Terrain for Corridor Point Control

I have a number of legacy InRoads SS2 projects where the project data will have to be moved to the current version of ORD.  The designer(s) at the time made extensive use of feature point controls as well as other advanced SS2 features.  Without maintaining a SS2 computer and license for ever so that in the future, the legacy design can be reused as in BIM, What is the best way to handle this legacy data?

Bentley has been blowing the BIM horn a lot lately, so I am wondering how that they are handling this?  ORD must be able to read legacy data and convert it to the current version of ORD, what ever that version is as legacy data will be here for a long time, or is BIM just a bunch of hot air?
