As part of neutron-nova parity effort it was decided to implement a Nova-network to Neutrom migration.
This migration will allow an administrator to switch network manager of a running virtual machine instance
from Nova-network's one to Neutron.

Current plan:
Juno-1: Flat Nova to Flat Neutron Migration
Juno-2: VlanManager to Neutron
Juno-3: Multi-host migration

Things to be discussed:

1. Key points
- Control plane outage will be necessary:
- Needed to ensure resources are properly transitioned from Nova to Neutron
- Instances should stay running and not need restarting.
- Brief data plane outage is possible as some L3 services are transferred:
- Routing

2. Migration process
- Nova API extension similar to instance live-migration?

3. Migration components
Nova side - ?
Neutron side - ?

4. Possible restrictions?
Nova side -
Neutron side -
