Update-SPSolution

 

Applies to: SharePoint Server 2010, SharePoint Foundation 2010

Topic Last Modified: 2011-01-21

Upgrades a deployed SharePoint solution.

Update-SPSolution [-Identity] <SPSolutionPipeBind> -LiteralPath <String> [-AssignmentCollection <SPAssignmentCollection>] [-CASPolicies <SwitchParameter>] [-Confirm [<SwitchParameter>]] [-Force <SwitchParameter>] [-GACDeployment <SwitchParameter>] [-Local <SwitchParameter>] [-Time <String>] [-WhatIf [<SwitchParameter>]]

The Update-SPSolution cmdlet upgrades a deployed SharePoint solution in the farm. Use this cmdlet only if a new solution contains the same set of files and features as the deployed solution. If files and features are different, the solution must be retracted and redeployed by using the Uninstall-SPSolution and Install-SPSolution cmdlets, respectively.

 

Parameter Required Type Description

Identity

Required

Microsoft.SharePoint.PowerShell.SPSolutionPipeBind

Specifies the SharePoint solution to deploy.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; a valid name of a SharePoint solution (for example, SPSolution1); or an instance of a valid SPSolution object.

LiteralPath

Required

System.String

Specifies the path to the solution package.

The type must be a valid path in either of the following forms:

- C:\folder_name

- \\server_name\folder_name

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.

noteNote
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.

CASPolicies

Optional

System.Management.Automation.SwitchParameter

Specifies that Code Access Security (CAS) policies can be deployed for the new SharePoint solution.

Confirm

Optional

System.Management.Automation.SwitchParameter

Prompts you for confirmation before executing the command. For more information, type the following command: get-help about_commonparameters

Force

Optional

System.Management.Automation.SwitchParameter

Forces the deployment of the new SharePoint solution.

GACDeployment

Optional

System.Management.Automation.SwitchParameter

Specifies that the new SharePoint solution can be deployed to the global assembly cache (GAC).

Local

Optional

System.Management.Automation.SwitchParameter

Deploys the solution on the local computer only.

Time

Optional

System.String

Specifies when the solution will be deployed. The default value is immediate deployment.

The type must be a valid DateTime value, in the form 2010, 5, 1.

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
