Hi I am currently using grizzly with nova-network (flat dhcp network without vlans). I have tried to migrate to quantum without breaking my instances but it is not so trivial. Could you please point out some howtos/manuals or at least let me know whether it is actually possible? I can replace old instances with new ones but during the migration all of them must have network connectivity. I would like to avoid migrating data from nova to quantum database. Replacing instances is probably easier for me. regards Maciej Gałkiewicz -------------- next part -------------- An HTML attachment was scrubbed...
