Upgrade Notes
- DB migration from the previous releases (icehouse or havana)
- In Icehouse or Hanava releases, the db migration operation is optional. If your Neutron database is not stamped (i.e., there is the db migration version info), please make sure to "stamp icehouse" before running the upgrade db migration to Juno.
- To check if your database is stamped, run the following command:
neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file <your plugin config file> current
- If the output of the current version is None, please run:
neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file <your plugin config file> stamp icehouse
- and then run the db migration for upgrading Juno:
neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file <your plugin config file> upgrade juno
- A list of all updated, deprecated or removed options in neutron can be found at: http://docs.openstack.org/trunk/config-reference/content/neutron-conf-changes-master.html
- Attribute level policies dependent on resources are not enforced anymore. Meaning that some older policies from Icehouse are not needed. (e.g. "get_port:binding:vnic_type": "rule:admin_or_owner").
- The following plugins are deprecated in Juno:
- Cisco Nexus Sub-Plugin (The Nexus 1000V Sub-Plugin is still retained and supported in Juno).
- Mellanox Plugin
- Ryu Plugin
- XML support in the API is deprecated. Users and deployers should migrate to JSON for API interactions as soon as possible since the XML support will be removed in the Kilo (2015.1) release.
