How can I update my Android Things preview 1 with preview 2? Is there an automatic OTA available or isn't this possible right now, so that I have to flash the sdcard (from my Raspberry Pi)?

EDIT1:
Currently, OTA is not available.You have to download preview 2 binaries manually and flash to sdcard.
EDIT2:(2017 Jun 30)
Now,OTA is available using androidthing console.
For OTA automatic updates, you have to create factory image then download it and flash it on your sdcard/board. Thats it, from next time onwards whenever there is OS/security update.Updates will be downloaded and install automatically.Also you can update your applications from console.See below image and for more info refer.

It was mentioned at IO 2017, OTA updates will be available via the IoT Developer Console. However I believe now because it's in developer preview, these features are not available.

The IoT Developer Console is the best place for developing Android Things or Weave on your devices.
More info in the docs as always: https://developers.google.com/iot/dev-console/
