Procedure

Service meshes of the Basic edition supports canary upgrades. To upgrade a service mesh, install the new Istio version's control plane to coexist with the old version. Label the namespace with the new revision. Restart some pods so that their sidecar proxies communicate with the new version, and then restart all pods to migrate all traffic to the new version. When the upgrade is complete, you can uninstall the old version.

Note that when the new version is being installed, istio-ingressgateway and istio-egressgateway of the new version are also installed, and the gateways of both versions work concurrently.
