=== 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()] to reseed the database copies.
For details, see xref:clustering/databases.adoc#recreate-databases[Recreate databases].

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, which may include data inconsistency between cluster members.
