 * The CSV data is clean/fault-free (nodes are not duplicated and relationships' start and end nodes exist).
 This tool can handle data faults but performance is not optimized.
 If your data has a lot of faults, it is recommended to clean it using a dedicated tool before import.

 === Usage and limitations
 
-[WARNING]
-====
 The importer works well on standalone servers.
 
-In clustering environments with multiple copies of the database, the updated database must be used as a source to reseed the rest of the database copies.
-You can use the procedure xref:procedures.adoc#procedure_dbms_cluster_recreateDatabase[`dbms.cluster.recreateDatabase()`].
-For details, see xref:database-administration/standard-databases/recreate-database.adoc[Recreate a database].
+To safely perform an incremental import in a clustered environment, follow these steps:
+
+. Run the incremental import command on a single server in the cluster. 
+This server can then be used as the xref:clustering/databases.adoc#cluster-designated-seeder[designated seeder] from which other cluster members can copy the database.
+. Reconfigure the database topology to a single primary by running the xref:procedures.adoc#procedure_dbms_cluster_recreateDatabase[`dbms.cluster.recreateDatabase()`] procedure.
+. Then stop the database using xref:database-administration/standard-databases/create-databases.adoc#manage-databases-stop[STOP DATABASE].
+. Perform the incremental import on the server that hosts the database.
+. Then start the database with xref:database-administration/standard-databases/create-databases.adoc#manage-databases-start[START DATABASE].
+. Lastly, restore the desired database topology using xref:database-administration/standard-databases/alter-databases.adoc#[ALTER DATABASE].
 
-Starting the clustered database after an incremental import without reseeding or performing the incremental import on a single server while the database remains online on other clustered members may result in unpredictable consequences, including data inconsistency between cluster members.
