To upgrade plugins, upload a new version of the bundle that contains those plugins. You can them select which version of the plugin bundle is the active one (that is, the one that connectors or stages will use). If you select the new version, all connectors and stages immediately begin using the new versions of the plugins in the bundle. You can change the active plugin bundle version at any time.
Important: Changing your active plugin bundle will cause a restart of the Workflow Designer and Search App pods.
