Upgrade: Mitaka to Newton

This page contains notes specific to the Mitaka to Newton upgrade path. See the main OpenStack upgrade page for full coverage.

neutron-gateway charm options

Between the Mitaka and Newton OpenStack releases, the neutron-gateway charm added two options, bridge-mappings and data-port, which replaced the (now) deprecated ext-port option. This was to provide for more control over how neutron-gateway can configure external networking. Unfortunately, the charm was only designed to work with either ext-port (no longer recommended) or bridge-mappings and data-port.
