Can you upgrade powershell 5.1 to powershell 6?


Asked by Valentino Pittman on Dec 09, 2021 FAQ



PowerShell 6 today is a side by side version next to Windows PowerShell 5.1. That means on Windows you cannot just upgrade to PowerShell 6, you will need to install it, same as on Linux and macOS.
Moreover,
It means that you cannot upgrade PowerShell 5.1 to PowerShell Core 7.1. PowerShell 7 is installed on a computer apart from Windows PowerShell 5.1. In PowerShell 7.1, the developers added maximum compatibility with Windows PowerShell. So you can easily run your old PS1 scripts and cmdlets in PowerShell Core.
Also Know, Today Windows 10 and Windows Server 2019 ship with Windows PowerShell 5.1 as the default version. PowerShell Core 6 is a new edition of PowerShell that is cross-platform (Windows, macOS, and Linux), open-source, and built for heterogeneous environments and the hybrid cloud.
Subsequently,
Install the Windows Management Framework 5.1 MSU file. After the server restart, open the PS console and make sure that the PowerShell version has been updated to 5.1. If you have unsupported Windows 7 or Windows Server 2008 R2, you can upgrade the PowerShell version from 2.0 to 5.1 in the same way.
In this manner,
PowerShell 5 is part of the Windows Management Framework (WMF) version 5 package. WMF requires the .NET Framework 4.5 package to be installed. You will need to install this before upgrading if you're trying to upgrade a Windows 7 or Windows Server 2008 computer. If you have Windows 8 or Windows Server 2012 or higher, .NET 4.5 is already included.
