title: Migrating changes from a dev APEX app to production?
body: <p>I have a production copy of an Apex app, and a copy on which I made changes and developed it into a newer version. Now that I am done developing and testing, is there an easy way to import my changes to the production version? Note that I cannot simply replace the production model with my new app. Do I have to make all those changes individually now on the production app?</p>
