If Elasticsearch is empty, this command will create the necessary indices
and then import data from the database into those indices.
This command will also upgrade indices if the underlying schema has been
changed since the last run. Index upgrades erase index data.
Even if creating or upgrading indices is not necessary, data from the
database will be imported into the indices, unless overriden with --no-import.
