Rename an IIS Web Application with PowerShell

Want to rename an IIS Web Application on a Windows 2008 R2 server? It’s not possible from the GUI, but it’s simple to accomplish using PowerShell. First, let’s create a web application in an existing website and then verify it exists:

Import-Module WebAdministration
New-Item -ItemType Directory -Path d:\iis\robbinsapps

Get-ChildItem iis:\sites\mikefrobbins

Rename-Item 'IIS:\Sites\MikeFRobbins\RobbinsApps' 'RobbinsApps-Archive'
Get-ChildItem iis:\sites\mikefrobbins
