-With the customized default `sap-btp-manager` Secret, you can perform the following actions:
-
-* Migrate your service instances created, for example, in Gardener, to the Kyma environment.
-* Connect a namespace to a specific subaccount without creating a namespace-based Secret because the `sap-btp-service-operator` Secret already includes your custom credentials. See [Namespace-Level Mapping](03-22-namespace-level-mapping.md).

-> If you have created a new non-default SAP Service Manager service instance and used its credentials to create your customized `sap-btp-manager` Secret, you can delete your Kyma cluster associated with this Secret regardless of the existing service instances and bindings created in this cluster.
-> The undeleted service instances or bindings do not block the deletion of the cluster.
