In which phase of an Intune update ring do you test updates and identify issues before deployment?

The phase of an Intune update ring where you test updates and identify issues before deployment is the "Pilot" phase. Here are the steps:

1. Create an update ring: In the Microsoft Endpoint Manager admin center, create an update ring for Windows 10 and later. This is where you define when updates are delivered to devices.

2. Set the "Servicing channel" to "Semi-Annual Channel".

3. Set the "Windows readiness state" to "Pilot". This is the phase where you test updates and identify issues before deployment.

4. Assign the update ring to a group of devices that will be used for testing. These should be a representative sample of the devices in your organization.

5. Monitor the update process and identify any issues. You can use the "Update status" report in the admin center to do this.

6. Once you are satisfied that there are no issues, you can move to the next phase, which is "Broad deployment".
