I'd like to create a website with Drupal 8 Alpha 3. But I'd like to know for sure if it's possible to do a harmless upgrade to Drupal 8 Beta once that it's released.

I heard something about the Drupal 8 API being frozen, but after reading this article (http://buytaert.net/drupal-8-apis-are-freezing-but-not-frozen) i'm not so sure anymore.

Can anyone help out?

PS: The website i'm going to build is fairly simple (few content-types, views, blocks etc)

    The beta isn't out yet, this isn't answerable until it is...any answer would be pure speculation. Best advice - It'll probably be fine, but don't build anything mission-critical (read: anything that matters if you can't upgrade smoothly) with Drupal 8 until at least API freeze

  • Yeah, figured something like that. Thanks for confirming :)

  • "Confirm" is a strong word ;) That's just based on my experience with D8 so far - some of the core devs check the 8 tag here regularly, so hopefully you'll be able to get a more official response

    This question appears to be off-topic because it is unanswerable at this current point in time.

    We will not support migration from alphas. What happens from beta X to beta Y is not yet known either.

Upgrading from a previous 8.x version will be supported starting with the first beta.

Upgrading from 8.x-alpha will break, I know of at least one issue that will make major changes to the entity/node storage.

  • Do you have a link to that issue by any chance? I've got a couple of custom entities that will probably need to be updated

    Sure: drupal.org/node/2057401. It should only affect you if you support revisions.

  • Drupal.org/node/731724 will certainly not upgrade head to head
