Transferring Annotations from 900 to 950

[Galan-Ithaca]

I've had a PRS 900 for a few months. I just purchased a 950. I don't use Reader Library for managing my library -- I use Calibre.

Is there a way to transfer all the notes and highlights (annotations?) on books that I've already read on the 900 to the 950? Seems like there should be a way to transfer certain folders or files on the 900 since all that activity is stored on the 900. I think the data is found in the "Digital Editions" folder, but I'm not sure which ones to transfer.
