How might I import IIS handler mappings from another IIS instance on a different machine?

Question

I'm migrating from one computer to another and in order to serve up my web app locally IIS requires some handler mappings in order to serve .svc extensions. I found on the new computer I'm missing those mappings. I'd like to script the creation of these mappings so that it's reliably repeatable. I found there's a powershell command Get-WebHandler and New-WebHandler. I was hoping I could get the hanlder mappings from the remote (old) IIS instance and pipe that into the new hanlder command.

Can I reference a remote IIS machine with Get-WebHandler or is there another command I would use to get IIS settings that I would then pipe into Get-WebHandler?

The *-WebHandler cmdlets don't work against a remote server, so you can not pipe existing handlers into New-WebHandler.

There are some hacks you can do:

• Copy the node from ApplicationHost.config on the old server to the new server.

• Get the output from Get-WebHandler into a csv file. Use that file to create new handlers on using New-WebHandler. This requires some coding.

• Create a PowerShell script from scratch to create your custom handlers with New-WebHandler. You could use pipe the output of Get-WebHandler from both servers into a text-file and do a Diff, so you can find what is different.

• Move custom handlers into the web.config of your site and the copy the site.
