+##### Default Database Name
+
+To execute this script, it may be necessary to set the default database name in Neo4j.

+In our deployments there are cases where the database is called `neo4j` (used by default) and in other cases `graph.db` (accidentally happened when we loaded the database into a new cluster).
+
+In the new deployment with Helm, we set the default database name by the environment variable `NEO4J_dbms_default__database` in the Helm `values.yaml`.
