Note: 5.1 Projects that Integrated Analytics Before September 8, 2015 Unity Analytics SDK will now support 4.x–5.1 versions. The previous 5.1 integration “PlayerSettings” copy-and-paste ProjectID method will still work, but we are discontinuing support for it. Refer to Analytics Forum for more information.
The process is divided into three general steps:
Removal of existing Unity Analytics Project ID
Re-integration of Unity Analytics
Updating of Advanced Integration events
Open Unity Editor 5.1 and select your existing Analytics project. Locate your Cloud Project ID in Player Settings. Choose Edit->Project Settings->Player, which opens the Player Settings. Delete your Cloud Project ID
If you did any existing Advanced Integration previously, you will also need to update the namespace and the calls to use the updated 4.x–5.1 SDK syntax.
