Migrating topics made by producers to Strimzi's KafkaTopics

[apolienko]

Hey!
I have a qustion and I didn't find anything about this problem.
Could anyone recommend the best approach to solve this problem.

We have Strimzi cluster and all topics were created by producers.
We didn't use KafkaTopic CRDs. But now it is obvious that we need to configure topics withj KafkaTopic CRDs. Is it possible to create topics with the same names and migrate origin topic data --to--> strimzi topic?

Or somehow tranform topics to manage them with strimzi ?

Thank you!

Why do you think it is obvious? You can use Strimzi without the Topic Operator or with the Topic Operator managing just some of the topics. It is completely up to you.

If you want to start using the KafkaTopic resources for existing topics, you just need to create the KafkaTopic resource with the same configuration it has: https://strimzi.io/docs/operators/latest/full/deploying.html#proc-converting-non-managed-topics-str. The chaoter before that describes the opposite process.
