Migrating the Neutron backend to OVN in production

OVN is cool. It’s been the default Neutron driver upstream for 2 years and most new features are being implemented in this mechanism driver. It has matured in the last few years and naturally operators will soon need to switch the driver in their deployments. Since networking is an essential piece in the whole ecosystem, it’s challenging to replace the networking backend while instances are up and using the overlay networks. The goal of this talk is to present what happens under the hood during the migration from the agent-based architecture using OVS, L3 and DHCP agents to a deployment using OVN for the overlay networks. The talk will highlight the current weak points in this migration process and will discuss what considerations need to be taken when planning for the migration.
