I've been checking out sails js and wanted to try the associations on the new version 0.10. How do I upgrade my project to version 0.10?
The best way is to create a new Sails project and copy your old controllers, policies, views, services, and assets over. As far as I know, there's no direct "upgrade" method from 0.9.x to 0.10.x.
Kevin Kao give a good answer for the start.
There is a part in the docs you should look after copying all: http://sailsjs.org/#/documentation/concepts/Upgrading
I recently posted to the Sails Google Group about this. My post is a basic procedure that follows Kevin's suggestion.
It might help to have a quick look:
