How to perform an in-place upgrade of Powershell

02 July,2013 by Jack Vamvas

Is an  in-place upgrade from Powershell 2.0 to Powershell 3.0 possible?

Yes , it’s possible to use your existing Powershell 2.0 installation to complete the .Net 4 prerequisite  and the Powershell 3.0 install


--install dotNet , the /q switch suppress the install windows. If testing I don’t use the /q switch 
dotNetNet4.exe /q /norestart

--install Powershell with the Windows Stand Alone updater
Wusa Powershell3.0.msu /quiet

--To complete the install exit  Powershell 


Use the  command line driven approach to install\upgrade Powershell 3.0 on either one server or create a script for multiple installations.
