Identity

Required

Microsoft.SharePoint.PowerShell.SPUserPipeBind

Specifies the GUID or login name of the user to be returned.

The type must be a valid login name or GUID of the user, in the form DOMAIN\username or 1234-5678-9876-0987.

NewAlias

Required

System.String

Specifies the new login name of the user account.

The type must be a valid login name, in the form DOMAIN\username.

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.

IgnoreSID

Optional

WhatIf

Optional

System.Management.Automation.SwitchParameter

Displays a message that describes the effect of the command instead of executing the command. For more information, type the following command: get-help about_commonparameters
