From what i have seen, the audio edits, as in cuts and cross fading's etc, were transferred over in demos of the AAF import and export feature, but i'm not so sure about other session data like clips for multiple takes. It seems like it still would take time to go and find the different takes manually from the original pro tools audio folder and to drag and drop the audio into layers on studio one channels individually. Also, 'm not sure about how groupings for multiple tracks would be transferred over either.
