I am using Self Managed in OpenShift and right now using Camunda 8.5. I have more than 500 active instances running. What is the step by step procedure to upgrade from 8.5 to 8.6
Can someone point me the right step by step documentation or help me with the procedure please

  1. How my Kubernetes cluster gets updated
  2. Zeebe Client get updated
  3. Running instances getting updated

There is a major change, Spring Zeebe SDK replaces the Community project. you need to modify the code.
