In Powershell, how do I copy/paste a file, if file already exists, to roll the new copy of the file?
<p>I am running a powershell script, with the following</p>

<p>Copy-Item -Path c:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config -Destination c:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.orig</p>

<p>If the machine.orig already exists, how can i make it copy it to machine.orig1, and if that already exists, machine.orgin2?</p>
