I just realized that there is a feature to utilize anki Droid as default flashcard program. I have it set up that new cards move over, however I don't know how to move existing cards. What am I missing?
For that, you'd need to temporarily disable AnkiDroid integration, then export your flashcards to a text file - you can reimport that into Anki as tab-delimited text. (and then turn back on AnkiDroid integration to proceed with creating new cards in Anki)
