We stage all changes on a 'develop' branch and run the same exact build process(thanks to bamboo) and deploy to the staging server. If QA passes, then we just merge the changes to master, push and deploy to production servers. Bamboo has a nice variety of test suites you can run too. I really like that git(via bitbucket) and bamboo notify hipchat of any build failures/updates so we can respond immediately if something serious actually goes wrong.
