PowerShell 7.0 – Cmdlet Compatibility

In my first post about PowerShell 7.0, I made mention of a major issue that most likely prevent adoption of PowerShell 6.x by Windows system administrators. This issue was the loss of functionality in 6.x, specifically that some cmdlets would not be available due to 6.x being built on .NET Core. The release of 7.0 is meant to help address this, which is the intent of this post.

Cmdlet Compatibility Approach

In reviewing the compatibility for 5.1 and 7.0, I used the management server in my home lab. This is a Windows Server 2019 virtual machine, so it shares the common set of cmdlets that Windows 10 has. As a management server, it also has some additional modules/cmdlets available:

  • Windows Server Role-based modules such as ActiveDirectory and DnsServer
  • SQLPS from the installation of SQL Server 2014
  • cmdlets associated with VMware’s PowerCLI
  • cmdlets associated with ChefDK
  • AWS’s PowerShell module

While not comprehensive, this does give good coverage of built-in, Microsoft-provided and third-party provided items.
