	// A value that indicates that minor version upgrades are applied automatically to

	// soon as possible. If moving this window to the current time, there must be at
	// least 30 minutes between the current time and end of the window to ensure
	// pending changes are applied. Default: Uses existing setting Format:
	// ddd:hh24:mi-ddd:hh24:mi Valid Days: Mon | Tue | Wed | Thu | Fri | Sat | Sun
	// Constraints: Must be at least 30 minutes
	PreferredMaintenanceWindow *string
