Update rollout plans in the Google Admin console allow administrators to gradually roll out ChromeOS updates to a subset of devices first. This allows for testing in a controlled environment before deploying to the entire fleet, reducing the risk of unexpected issues impacting all devices. Steps to add an update rollout plan: * Access Google Admin Console: Sign in with your administrator credentials. * Navigate to Device Management: Go to Devices > Chrome > Settings > Updates. * Create Rollout Plan: Click on "Add an update rollout plan." * Select Devices: Choose the specific devices or organizational units (OUs) to include in the initial rollout. * Set Timeline: Define the start and end dates for the rollout. * Save and Apply: Save the plan and apply it to the selected devices.
