Migrating from Helm chart to Confluent for Kubernetes

Currently, we are using Kafka version 2.8 and Confluent Platform version 6.2.2, We are planning to upgrade Kafka version to 3.2.x and Confluent Platform version to 7.2.x.
After Confluent Platform version 6.2.x confluent stopped support for helm charts and now we need to migrate to kubernetes operator to use latest kafka versions.

Is there any document for migrating from helm charts to kubernetes operator and is there any risk involved like data loss?


You should use whatever tools you use to currently backup any persistent volumes in k8s, then install the operator with those restored
