upgrade:
- Ocata requires that your deployment have created the
cell and host mappings in Newton. If you have not done
this, Ocata's `db sync` command will fail. Small deployments
will want to run `nova-manage cell_v2 simple_cell_setup`
on Newton before upgrading. Operators must create a new database for cell0
before running `cell_v2 simple_cell_setup`. The simple cell setup command
expects the name of the cell0 database to be `<main database name>_cell0`
as it will create a cell mapping for cell0 based on the main database
connection, sync the cell0 database, and associate existing hosts and
instances with the single cell.
