I originally used Tensai AI Plugins to convert my files. It's a hit and miss situation. Some of the .fh9 files were too old or complex to convert. My best solution was found in my old macs lying in my garage, luckily It hadn't been updated since 0S9. I reopen the files using freehand, resave them into .pdf or .ill sometimes to .eps and then reopened the in illustrator 6, then again in CC. Not all converted accurately and many times better than the extension in Illustrator.
