[openstack-dev] [Neutron][LBaaS]Removing LBaaS v1 - are weready?

Just for clarity, V2 did not reuse tables, all the tables it uses are
only for it.  The main problem is that v1 and v2 both have a pools
resource, but v1 and v2's pool resource have different attributes.  With
the way neutron wsgi works, if both v1 and v2 are enabled, it will
combine both sets of attributes into the same validation schema.

The other problem with v1 and v2 running together was only occurring
when the v1 agent driver and v2 agent driver were both in use at the
same time.  This may actually have been fixed with some agent updates in
neutron, since that is common code.  It needs to be tested out though.

Thanks,
Brandon

With 3rd party Lbs I would assume vendors proving those scripts to make sure their particular hardware works with those. If you indeed need a migration from LBaaS V1 namespace -> LBaaS V2 namespace/Octavia please file an RfE with your use case so we can discuss it further…
