Metalogix: how to copy a workflow from a list to another list in another site collection?

Hi everybody,

I have 2 Web Application with Nintex Forms & WFs.

The first WebApp is for Production, the second for development.

When a list Form & WF is developped and successfully tested, I migrate the associated Form & WF to the Production WebApp.

I don't want to use the Nintex export buttons, I want to use Metalogix which is supposed to migrate Nintex WFs...

Can you share your experience about that ?

Thanks

Charles
