You may have issues executing the PowerShell script "3Tconverter.ps1".
"File 3Tconverter.ps1 cannot be loaded. The file is not digitally signed. The script will not be executed on the system."
For some reason the script is not being trusted by your system. It may be because of the way it was copied over.

From the PowerShell window, instead of using "Set-ExecutionPolicy RemoteSigned" as recommended in the mmigration guide, use this command instead:
(Enter Y when prompted).
Now you should be able to execute the script as it is not doing certificate checking.
