[Dr. Drib]

This may sound somewhat complicated, but it's really very simple:


1) Plug in your OLD ebook reader and let calibre notice it.
2) Sort all the ebooks on the list (your ebooks will have a check-mark) and highlight them. (In other words, group all of the check-marked ebooks together.)
3) Now that the ebooks on your old device have been highlighted (step 2) and are listed together, go to Edit Metadata and create a unique tag that will identity every one of those highlighted ebooks.
4) Create a Virtual Library, using that unique tag to isolate those ebooks from the rest of the ebooks you have on calibre.
5) safely remove your old device.
6) Plug in your NEW device and let calibre recognize it.
7) Highlight all of the books that are listed in your newly-created Virtual Library.
8) Load (copy) them to your new device.
9) You're finished.


IMPORTANT: This is assuming that ALL your ebooks have been put on calibre and that you have taken care of DRM issues beforehand.
