Performing the upgrade using Helm charts

Typical upgrade steps

A lot of the upgrade steps can be performed without impact on your users. Basically, the deployment or upgrade of components is split in two actions:

Configuration changes, such as added or changed configuration parameters, including the new component’s version
Deployment of the upgraded component, using the helm upgrade command.

Axual Platform 2023.4 is installed using Axual helm charts version 0.17.0

Update the Axual helm repository to download the latest charts available
```
helm repo update
```

Upgrade Axual Platform

helm upgrade --install platform axual-stable/platform --version=0.17.0 -n kafka

This command will restart the all axual-platform pods.

Verify the upgrade by checking the pods and their images:

[clusterShortName]-clusterbrowse pod uses image: docker.axual.io/axual/cluster-browse:1.6.5
[clusterShortName]-distributor-connect pod uses image: docker.axual.io/axual/distributor:5.2.0
[tenantShortName]-[instanceShortName]-rest-proxy pod uses image: docker.axual.io/axual/rest-proxy:1.8.1
[tenantShortName]-[instanceShortName]-schema-registry-master pod uses image: docker.axual.io/axual/schemaregistry:5.6.0
[tenantShortName]-[instanceShortName]-schema-registry-slave pod uses image: docker.axual.io/axual/schemaregistry:5.6.0
selfservice-aom pod uses image: docker.axual.io/axual/operation-manager:1.5.4
selfservice-api pod uses image: docker.axual.io/axual-api:8.1.0
selfservice-streambrowse pod uses image: docker.axual.io/axual/stream-browse:1.5.5
selfservice-ui pod uses image: docker.axual.io/axual/axual-frontend:9.2.0

Once restarted, verify everything is running fine before moving to next step.

No other steps are required to upgrade or configure the platform components.
