As part of the upgrade process from 0.20 -> 0.25, I first updated the operator version to 0.22. I was trying to use the api-conversion tool to update the CRDs but I ran into this problem. The kafkarebalances artifact that's there in the cluster is this.... apiVersion: apiextensions.k8s.io/v1

Thanks in advance. ::::UPDATE:::: I ran it a second time and saw this, Every other time after that it was picking up a random CRD and complaining about the same thing. Please advice. |

You need to have the CRDs from 0.22 installed before running the conversion tool. If you want to upgrade from 0.20 or 0.21 to 0.25, it should be possible. But you have to first install the 0.22 CRDs, do the CRD upgrade and then upgrade the operator to 0.25 (including 0.25 CRDs). Or you can simple first upgrade to 0.22, then use the CRD upgrade tool and then upgrade to 0.25. |

I started here -> https://strimzi.io/docs/operators/0.25.0/deploying.html#assembly-upgrade-str. The first step - Upgrade Strimzi to 0.22. The second step - Convert the custom resources to v1beta2 |

Ah, ok ... I think you downloaded the source code which is IIRC wrong for the 0.22 release. Download the release artifacts: https://github.com/strimzi/strimzi-kafka-operator/releases/download/0.22.0/strimzi-0.22.0.zip and use those. That was a bug in the 0.22 release. |

That was it. Thanks Jakub. I wonder how come no one else came up with this issue earlier? Is the typical deployment flow different in the most common cases? |

It is known that the release branch has wrong files. But I'm not aware of anyone downloading the source files instead of the release artifacts from the release page - so that was why I guess I was a bit confused :-). This is fixed in later releases. |
