In which phase of an Intune update ring do you deploy updates to additional rings, or device groups, one at a time?

The phase of an Intune update ring in which you deploy updates to additional rings, or device groups, one at a time is the "Broad Deployment" phase.

Here are the steps:

1. Start with the "Pilot" phase: This is where you deploy the update to a small group of selected devices to evaluate the update's performance and any potential issues.

2. Move to the "Broad Deployment" phase: After successful testing in the pilot phase, you gradually deploy the update to additional rings or device groups. This is done one at a time to manage the risk and impact of the update.

3. Monitor and review: After each deployment, monitor the update's performance and resolve any issues before moving on to the next group.

4. Complete the deployment: Continue this process until all rings or device groups have received the update.
