Upgrades a single Project Web App instance and its associated Project Web App database.

Upgrade-SPProjectWebInstance [-Identity] <ProjectSitePipeBind> [-AssignmentCollection <SPAssignmentCollection>] [-Confirm [<SwitchParameter>]] [-WhatIf [<SwitchParameter>]]

Use the Upgrade-SPProjectWebInstance cmdlet to apply upgrade changes to a single Project Web App site within a SharePoint Server 2013 farm.

If you apply an update to Project Server 2013, applying the update only updates the binaries on the server, until you run PSConfig. If you do not run PSConfig, and run the Upgrade-SPProjectWebInstance cmdlet instead, it upgrades the Project Web App database that is associated with the specified Project Web App instance to match the version of the updated binaries.

Upgrade-SPProjectWebInstance only upgrades the Project Web App database. It does not upgrade any SharePoint Server 2013 databases.

Windows PowerShell with Project Server


Parameter Required Type Description




Specifies the location of the Project Web App instance where the upgrade changes are to be applied.




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.

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.


Upgrade-SPProjectWebInstance -Identity "http://servername/pwa"

This example upgrades the Project Server 2013 database associated with the Project Web App instance at the specified URL.
