Nova will require cellsv2 setup before/during the upgrade to ocata. At this time, the following are known, but more steps are likely to materialize before the ocata release:
Scott you didn't ask a question?
To summarize the release notes:
For an upgrade to Ocata of a non-cells deployment, the following steps are needed in Newton:
1. Create a new database for cell0 based on the current name of the api database: <API database name>_cell0. If the api database is named nova_api, then the cell0 database should be named nova_api_cell0.
2. Run the simple cell setup command: nova-manage cell_v2 simple_cell_setup --transport-url <transport url for message queue>.
An upgrade of an existing cells v1 deployment requires different, more complex steps, so let us know if that info is needed.
There's also an enhancement to the simple_cell_setup command in Ocata that can pick up [DEFAULT]/transport_url from the nova.conf (instead of only the command line), so I'm going to try to get that backported to Newton for use. I will update here if that happens.

Hello, could you please provide more info about this bug. Is it going to be a part of OSP 11 or not? It would help me to decide how I will handle the documentation for this issue. Thanks a lot.

RHOSP 11 will deploy a so called "cell of one", a single cell deployment. This is because this is mandatory for Nova from Ocata and beyond. This is mostly plumbing from a user perspective, but should be reflected in any manual configuration or architecture documentation so that they are able to understand what is being deployed.
Deployment and configuration of multi-cell environments is not addressed in this release.
There will be no manual configuration required. OSPD will deploy a single cell setup for a fresh install or upgrade RHOSP 10 to a single cell.
Upstream docs describe the architecture quite well IMO:
By manual configuration I was referring to the fact that in addition to the director-based installation documentation the docs folks maintain these guides which will likely need updates:
Manual Installation Procedures
Thanks, guys, for your quick reply. I highly appreciate that.
Ah, ok. The manual setup procedures will need to be updated for both cell_v2 setup and the placement api setup.
Can this be moved to POST or MODIFIED?
