Hi team i am working on istio upgrade from 4.5 to 12.5, i am using egressgateway, ingressgateway and sidecar, and this had been provisioned via terraform now due to some limitations i cant use terraform need to upgrade it manually, any help?
Kiran Sharma:
@unnivkn i tried all but it only upgrade istio plane, not the docker images for aubsets like ingress

Oh, this will be a pain! We do Istio upgrades one version at a time and we rebuild the K8s cluster basically. Istio Canary upgrades are rubbish because they do not upgrade sidecars. You msut scale all deployments down and then scale them back up to pick up the new version.
