RootObject

Required

Microsoft.SharePoint.Administration.IUpgradable

Specifies a SharePoint object where you check for which upgrade actions are outstanding for that object based on its current upgrade status. This object must be inherited from IUpgradable.

AssignmentCollection

Optional

Microsoft.SharePoint.PowerShell.SPAssignmentCollection

Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

Note:
When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.

Recursive

Optional

System.Management.Automation.SwitchParameter

Specifies whether to perform the same pending upgrade action checks on each IUpgradable object that occurs under the RootObject parameter that is specified.
