Objective:

To document the upgrade under these characteristics:

Method: Helm
Initial Operator Version: 4.5.4
KES with Vault as KMS solution
Initial KES Version: v0.18.0
Final Operator Version: 5.0.11

Steps:

Have Cluster with Initial Versions
Make sure to keep KES Version and MinIO Version in the Tenant Spec, example:

spec:
  image: minio/minio:RELEASE.2023-10-16T04-13-43Z
  kes:
    image: minio/kes:v0.18.0

By doing so, the Operator will retain these versions throughout the upgrade process.

Then you can upgrade Operator Version via Helm Chart or Kustomization
Once you have upgraded to the latest version of the Operator, such as 5.0.11, you can proceed with upgrading MinIO and KES. Keep in mind that the configuration for KES may change over time, so ensure that your secret for KES configuration is updated accordingly. You can obtain the latest KES configuration from here: https://github.com/minio/kes/blob/master/server-config.yaml
