[ORD 10.08 C#] Is there a way to determine which version of Civil Data is contained in a DGN? V8 based or CONNECT based

Is there a way to detect what version of Civil data is contained in a  dgn file? I thought maybe looking at the dgn file version would point me in the right direction with 8.1xx being V8based & 8.2xx being CONNECT based. But looking through a project when I open some V8 files versioned 8.202 I get the message about Obsolete Civil Data Found.
