[Openstack] nova-network -> neutron migration docs and stories?

Hi Andrew,

NeCTAR published a suite of scripts for doing a nova-network to neutron
migration: https://github.com/NeCTAR-RC/novanet2neutron

IIRC, another organization reported success with these scripts a few months
ago on the openstack-operators list.

I'm currently doing some trial runs and all looks good. I had to make some
slight modifications to account for IPv6 and floating IPs, but the scripts
are very simple and readable, so it was easy to do. I'll probably post
those modifications to Github in the next week or two.

We'll be doing the actual migration in May.

Hope that helps,
