I think I understood from Jimmie that Bentley SS4 will need to convert some files that contain certain functionalities - that not all files will need to be converted.
Could you elaborate on exactly the nature of the conversion?
Presumably, once converted, it cannot be opened again in SS3?

SS4 will irreversibly alter the Civil Geometry in a DGN file. When opening a SS3 file with SS4 the user will be prompted to either upgrade the geometry or open the file as read-only. The file can be opened with SS3 after the upgrade but it will present a dialog notifying the user that the Civil Geometry is incompatible. In my opinion any project using OpenRoads SS3 Technology should be immediately switched to SS4. Just upgrade everyone's computer and move on because SS4 is really just SS3-v2.0.
