Migration from Midonet to OVN

Hi all,

We are planning a migration from Midonet to OVN. The general idea is to:

- pause neutron - do a `neutron-ovn-db-sync-util` - change networks/ports to geneve/ovs - hard reboot the instances

We are wondering if anyone has done a migration like this before, and will like to share their experiences.

Any input will be greatly appreciated.

Regards, Jake
