Cross SSO and vCenter VMotion using PowerCLI

http://cloudmaniac.net/using-powercli-to-vmotion-vm-between-different-sso-domains-vcenters/

Roman Decker wrote an article about how to move virtual machine between vCenters that are not part of the same SSO domain, using PowerCLI.

I felt like it needed some adjustments to be more dynamic and interactive, so many of the hard coded bits I decided to make the script ask for at runtime.

Credit for the original script goes to Roman Decker.

The script is not perfect, so use at your own risk. I would like to make fault correction for failed login. I just did not have any more time.

Use at your own risk. Good luck.

The Script
