+### Kotsadm
+
+When you install kURL with `ekco.kotsadmShouldDisableManagement` set to `false`, the EKCO operator ensures that necessary KOTS components run with multiple replicas for high availability.
+
+For Kotsadm v1.89.0+, the EKCO operator enables a high availability three-replica StatefulSet for the database when at least three nodes are healthy and the OpenEBS localpv storage class is available.

 ### TLS Certificate Rotation
 
 EKCO supports automatic certificate rotation for the [registry add-on](/docs/install-with-kurl/setup-tls-certs#registry) and the [Kubernetes control plane](/docs/install-with-kurl/setup-tls-certs#kubernetes-control-plane) since version 0.5.0 and for the KOTS add-on since version 0.7.0. For more information about automatic certificate rotation for the KOTS add-on, which is used by the Replicated app manager, see [Using TLS Certificates](https://docs.replicated.com/vendor/packaging-using-tls-certs) in the Replicated documentation.
