Googling for nova-network migration advice gets me a lot of hits but many are fragmentary and/or incomplete I know that lots of people have gone through this process, though, and that there are probably as many different solutions as there are migration stories. So: If you have done this migration, please send me links! Blog posts, docpages that you found useful, whatever you have to offer. We have lots of ideas about how to move forward, but it's always nice to not repeat other people's mistakes. We're running Liberty with flat dhcp and floating IPs.
