Deploy, test, and extend

Test throughly

Once you've updated your app, test it thoroughly to verify that it works as expected and that you haven't introduced any regressions.

Be sure to use multiple environments, data sets, and end-user personas, e.g. credentials with different roles, rights, and responsibilities. Go through the entire lifecycle, by having a new test user acquire the app for the first time, as well as an existing user (who already consented) trying to use the app again.
Deploy staged updates

Consider deploying your updates in stages. A limited roll-out to a small set of friendly users can help identify glitches and other potentially-embarrassing issues. This also gives you a chance to monitor initial reception and feedback.

If the initial roll-out goes well, monitor progress as you deploy to larger audiences.
Explore new value

Now you've made the switch to Microsoft Graph, it's never been easier for you to unlock many more datasets and features that are now at your fingertips. Check for new datasets and capabilities regularly.
