Upgrade the Proxy
Uyuni Proxies are managed in the same way as clients.
Before you perform any proxy update, schedule a maintenance window. The clients registered to Uyuni through the proxy will not be able to connect to Uyuni while the update is in progress. For more information about maintenance windows, see administration:maintenance-windows.adoc.
The upgrade procedure to 2021.09 can either be a major or a minor upgrade. For more information, see the Uyuni 2021.09 release notes.
