+ * tenant. This script will do the following in the admin tenant:
+ *
+ * 1. Disable registration.
+ * 2. Create organization template roles and scopes.
+ * 3. Create organizations for existing tenants.
+ * 4. Add membership records and assign organization roles to existing users.
+ * 5. Create machine-to-machine Management API role for each tenant.
+ * 6. Create the corresponding machine-to-machine app for each tenant, and assign the Management API role to it.
+ *
+ * The `down` script will revert the changes.
