Typically it should only involve replacing your system folder, and possibly some small code changes. I think most people wouldn't need a full test environment, but if you have a high-traffic site, or some hardcore extended classes, it couldn't hurt.

See the upgrading section of the user guide for specific updates. http://ellislab.com/codeigniter/user-gui...ading.html
