When Atlas schedules required maintenance for your clusters, you can begin the maintenance immediately or defer it for one week. To learn more about how Atlas rolls out maintenance, see Manage Cluster Maintenance.
When maintenance is required:
Between 48 and 72 hours (2-3 days) before the scheduled maintenance, Atlas displays a banner in your project's cluster list showing the date and time when the maintenance is scheduled. Click Show Details to see the scheduled maintenance operations, such as MongoDB version updates, OS policy updates, or other maintenance types.
Atlas sends an email to users with the
Project Ownerrole and updates the Atlas UI to display the option to begin maintenance immediately or to defer maintenance for one week.Note
To configure how you receive scheduled maintenance window notifications, see Configure a Maintenance Window Alert.

Defer Maintenance
Use the following procedure to defer currently scheduled maintenance by one week. To automatically defer all future maintenance, enable auto-defer.
Note
Deferring Maintenance with Maintenance Waves Configured
You can only manually defer maintenance for projects with a maintenance wave configured if they are assigned to Last Wave. Atlas limits these projects to at most one manual deferral.
Note
You can defer a single project maintenance event up to two times.
