We're actively working on migrations as well. We submitted a PR recently to support specifying
a mac address on an interface to ease migration pain.

Subject: Re: DISCUSS : Vmware to Cloudstack migration support

If you are going from VMware to CloudStack Managed VMware, this is
something I have done quite a bit.  I even built a tool to do this:

Contribute to migrate2cs development by creating an account on GitHub.




This is not a polished product.  Well, it is pretty polished once you get
it setup, but the setup is a bit complicated to get started.

If you would like to use it, let me know and I will do what I can to get
you setup.
