# Migrate From Previous Istio Version
There is no upgrade path for Istio versions less than 1.7
There is no upgrade path for Istio versions less than 1.7.x. To successfully install Istio in the **Cluster Explorer**, you will need to disable your existing Istio in the **Cluster Manager**.
If you have a significant amount of additional Istio CRDs you might consider manually migrating CRDs that are supported in both versions of Istio. You can do this by running `kubectl get <resource> -n istio-system -o yaml`, save the output yaml and re-apply in the new version.
Another option is to manually uninstall istio resources one at a time, but leave the resources that are supported in both versions of Istio and that will not be installed by the newest version. This method is more likely to result in issues installing the new version, but could be a good option depending on your situation.

The Istio overpage provides a link to the Kiali dashboard. From the Kiali dashboard, you are able to view graphs for each namespace. The Kiali graph provides a powerful way to visualize the topology of your Istio service mesh. It shows you which services communicate with each other.
>**Prerequisite:** To enable traffic to show up in the graph, ensure you have enabled one of the [Selectors & Scrape Configs]({{<baseurl>}}/rancher/v2.x/en/istio/setup/enable-istio-in-cluster/#selectors-scrape-configs)options. If you do not have this configured, you will not see information on the graph.
>**Prerequisite:** To enable traffic to show up in the graph, ensure you have prometheus installed in the cluster. Rancher-istio installs Kiali configured by default to work with the rancher-monitoring chart. You can use rancher-monitoring or install your own monitoring solution. Optional: you can change configuration on how data scraping occurs by setting the [Selectors & Scrape Configs]({{<baseurl>}}/rancher/v2.x/en/istio/setup/enable-istio-in-cluster/#selectors-scrape-configs) options.
