``nova-manage db online_data_migrations [--max-count]``
Perform data migration to update all live data. Return exit code 0 if
migrations were successful or exit code 1 for partial updates. This command
should be called after upgrading database schema and nova services on all
controller nodes. If the command exits with partial updates (exit code 1)
the command will need to be called again.
``--max-count`` controls the maximum number of objects to migrate in a given
call. If not specified, migration will occur in batches of 50 until fully
complete.
