I installed Istio with istioctl and our cluster has multiple Istio control planes. So as part of upgrading to a new Istio version, I want to delete the older version. What is the recommended approach?

  1. istioctl x uninstall -f manifest
  2. helm uninstall (in my case this doesn't work as I'm not installing with helm)

Any other approaches?

  • BTW: istioctl uninstall --help, we use revisions thus we uninstall via istioctl uninstall --revision 1.2.3.
