Answer 1

1. Install ember-cli 0.2.7 globally
2. ember new demo-app
3. Edit your bower.json so that ember is 1.12.2 and ember-data is 1.0.0-beta.19.2
4. bower install
5. Edit your package.json so that ember-data matches version in bower.json
6. npm install
7. ember s
8. (Optional, but it will improve performance): Upgrade your project's ember-cli version as much as you would like to attempt. (expert step, unfortunately) (Technically it is possible to get all the way to ember-cli 2.5)
