File format migration paths for Instant Artist files

Instant Artist is an abandonware layout and publishing platform from the early 90s by Pixellite Group and Autodesk.

Its file formats include .sgn (signs), .ban (banners), .gc (greeting cards), .bc (business cards), .lth (letterheads), etc. They don't appear to open in contemporary software. I'd rather not emulate if I can avoid it. What are these files' possible file format migration paths, or are they proprietary and unable to be converted?
