Neutron-LBaaS to Octavia Migration Tool
This tool allows you to migrate existing, running load balancers from Neutron-LBaaS to Octavia. This is intended as a one-time migration tool used to move load balancers from being managed by Neutron-LBaaS to be managed by Octavia.
Warning
We recommend you make a backup of both the neutron and octavia databases before running this tool.
Warning
You must have the provider driver loaded and enabled in Octavia for the load balancer(s) you are migrating.
Note
This tool will not convert a load balancer from one provider to a different provider. It will only migrate a load balancer using the same provider in Neutron-LBaaS and Octavia.
Background
Neutron-LBaaS was deprecated during the Queens release of OpenStack.
Theory of Operation
Octavia is an improved superset of the Neutron-LBaaS API extension to Neutron. Because of this relationship the object model is very similar between the two. This tool will access the Neutron database (which contains the neutron-lbaas tables and records) and intelligently migrate the management records from the Neutron database to the Octavia database. The tool will also update neutron object ownership to reflect Octavia taking ownership for those objects.
Objects that will change ownership are: Neutron ports Neutron security groups
Usage
'--all' Migrate all neutron-lbaas load balancers
'--config-file' The path to the configuration file
'--lb_id <id>' Migrate one load balancer by ID
'--project_id <project_id>' Migrate all load balancers owned by this project ID
