With the support for MaintenanceControl in Service Fabric managed clusters, customers can define a recurring (daily, weekly, monthly) and custom maintenance window for their SFMC cluster resource, 
 as per their needs. All background maintenance operations will be allowed to execute only during this maintenance window. MaintenanceControl is applicable to these background operations:

 * Automatic extension upgrade
