Migrate to Windows Server 2012 Remote Desktop Gateway?

Hi folks,

We had a Windows Server 2008 R2 server with the remote desktop gateway role installed. How can I migrate the RDG role to a Windows Server 2012 machine?

I did not come across any documentation on this specific operation. We tried exporting the policy and configuration settings, but the XML file was not accepted for import in the 2012 RDG. I tried massaging the XML since there were a few differences, but it still did not take. We didn't see a powershell cmdlet for export/import operations either.

What we wound up doing was to recreate each CAP and RAP rule by hand on the 2012 RDG. Was there a better way to handle this?

Thanks!
