The docs have sections about upgrading Strimzi. Upgrades usually have to move from one version to the next eg 0.17 -> 0.18 -> 0.19. Jumping versions is not recommended, however it can be done if both versions share support for the same Kafka versions. Again though jumping versions is not recommended. |

Ok... @tomncooper - This morning I started an upgrade from 17 to 19 by following the strmizi recommended steps below. 7.1. Strimzi and Kafka upgrades Here are the steps I have followed.
After step 4 I started noticing that Kafka pods are going into crashloopbackoff, I was expecting them to get re-created as it should have only a single container without TLS. Following are the state of the pods and logs.
Please suggest. |

Same logs are observed.
This is for Kafka container inside my-cluster-kafka-0 pod

What do the Zookeeper logs look like. There was a ZK upgrade from 0.17 to 0.18 (IIRC) and this required custom code to deal with changes to the ZK snapshots. |

All the versions of the operator/applications/Kafka-bridge/jmxtrans are the recommended ones I have used. I am attaching the 18 operator file used. gcr-path in the file is my private folder path inside the |

Wow, this looks to be a good catch. Then if that is the case I believe my earlier upgrade from 17->19 is also because of the same Kafka app image. Let me check my images then which I have pulled and pushed into GCR. I will revert back on this. Thanks for today. |

Hi Scholzj,
Just a question, do we have any Strimzi documentation which talks about upgrade steps/guidelines from one version to the other.
I am looking for something from 0.17 to any other above versions.
Need some info around this.
