Set-ItemProperty working in PowerShell 5.1, but not in 7.0

I installed PowerShell 7.0 and started some testing. The following script works with no errors in PowerShell 5.1.

Import-Module WebAdministration

Set-ItemProperty "IIS:\Sites\TestSite" -Name physicalPath -Value "D:\Dev\Test\Website\WebSiteDown"

In PowerShell 7.0 I tried to change the import to use the updated "IISAdministration" module instead of the older "WebAdministration". I get the same error with both modules.

Set-ItemProperty: D:\Dev\OProTrunk\Website\WebSiteDown\OctopusCommand\Test.ps1:3
Line |
   3 |  Set-ItemProperty "IIS:\Sites\TestSite" -Name physicalPath -Value  …
     |  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | Cannot find drive. A drive with the name 'IIS' does not exist.

Both were running as administrator to be able to update the web site physical path. Do I need to format the property different with PowerShell 7.0?

As far as I can tell, you will need to interact with your compatibility session for Windows PowerShell here.

Import-Module WebAdministration
$session = Get-PSSession -Name WinPSCompatSession
$sb = {Set-ItemProperty "IIS:\Sites\TestSite" -Name physicalPath -Value "D:\Dev\Test\Website\WebSiteDown"}
Invoke-Command -Scriptblock $sb -Session $session

The IIS PSDrive is created by the WebAdministration provider. Since that provider only loads in Windows PowerShell (at least on my system), you will need to access it there.
