Upgrading strimzi operator from 0.25.0 to 0.26.1

[seemasanjaisinghani]

When we are upgrading strimzi operator from 0.25.0 to 0.26.1, it shows below exception in operator logs, looks like it is expecting kafka image 2.8.1

We don't want to move to kafka image 2.8.1 but we want to continue with 2.8.0, is it supported?

You can find the list of supported Kafka versions here: https://strimzi.io/downloads/ ... 2.8.0 is still supported (although obviously 2.8.1 has all king of bugfixes etc.). The error you have looks more like you didn't properly installed 0.26.1 ... how did you do it? You cannot just change the image, you need to install the new YAMLs.
