Over the last while my colleague Amanda and I have been collecting information to guide people through the upgrade to Sitecore 8 and plan for the new xDB.

WCF and CORS: “No ‘Access-Control-Allow-Origin’ header is present on the requested resource”
If you are building an Angular app (or other form of HTML5 web application) you are probably running controllers on JSON data to bind to repeaters and present to your users.
