The latter. If you think the documentation is deficient, please propose a patch 
that would clarify that.

[Openstack-operators] Neutron database upgrade kilo-liberty and parallel Alembic migration branches

2016-06-01 Thread Saverio Proto 
Hello,

reading this documentation page:

http://docs.openstack.org/mitaka/networking-guide/migration-neutron-database.html

I dont get what means having two parallel migration branches.

Do you have to choose one of the branches ? If yes how ?


Or it just means that some operations can be safely run when Neutron
Server API is running, (e.g.
neutron-db-manage upgrade --expand)

while other operations (e.g. neutron-db-manage upgrade --contract)
require the Neutron Server to be stopped ??

Anyone has some upgrade notes to share that can clarify the procedure ?

Thank you

Saverio
