Sorry if I missed the original discussion on that, but why is copying
the static IP configuraition even considered to be a good thing?

For one, it's unlikely that the IP address will remain valid in the
target environment.

For two, in a typical cloud setup static IP addresses are configured by
some sort of a cloud-specific management agent, and bypassing it is
likely to cause conflicts.

For three, network configuration is a notoriously complex thing.  I
think I can recall a dozen of network configuration systems in Linux
that claimed to provide the ultimate solution to all problems and none
that delivered to the promise.  I guess in Windows the situation is
hardly much simpler.  Creating yet another universal solution doesn't
appear to be in scope for v2v (if realistic at all); and I'm not sure
that having a very limited solution for a very basic use case only is
better than explicitly telling the user not to rely on v2v for network
configuration.
