The proxy is offline for only a short time. Mixed proxy-version environments You can run old versions of the proxy with new versions of the proxy on the same instance with the following limitations: If a proxy running the Geneva version of software is registered with the instance, you cannot use the instance to assign a default key. If you have assigned a default key using the instance, a Geneva version of the proxy cannot register with the instance. Update a proxy running on LinuxUpdate a proxy running on Linux.
