The selector in the top left shows your first ten apps in alphabetical order. Start typing an app name to choose a different app.
Use the dropdowns in the top right to select the version you'd like to upgrade from and the version you'd like to upgrade to. You'll see up to the oldest version your app can call.
The tool displays the number of changes that need to be made to update your app to the selected version.
Methods are color coded by the version affecting the call. Hover over the bar chart to see how many changes are in each version. The dates associated with each version are when the changes will be enforced for all apps.
The table shows the type of change (deprecation, new feature or change), which methods are affected, the number of calls made in the last 7 days, and the percentage of API calls affected by that specific change.
Note: For apps on v2.0, FQL will be deprecated with v2.1. If your app uses FQL calls, there is a second table below which will map calls to common Graph API calls that may replace it. But, not all FQL features are guaranteed to be supported in Graph API.
There's a few reasons why you might not see anything in the tool:
Only admins and developers of an app can view it in the tool. The selector shows your first ten apps in alphabetical order, once you start typing an app name, the tool will auto-completeThe call volumes for a method seem off. Why?
The logging is sampled and aggregated over the previous week. It's compared with the call volume to estimate how many of your calls could be affected by a given version change.
Note: Not all changes may affect each API call - use your best judgment on whether a particular change needs to be handled by your app. Be sure to test your API calls in the newer version to ensure it works properly.Where can I find more info?
