Cloud Proxies are upgraded to a compatible cluster version automatically after the cluster upgrade. Expect a downtime of one or two cycles, as the cloud proxy does not collect any data during this period. Data collection resumes after the upgrade is complete. In case the automatic upgrade fails, you can upgrade your cloud proxy manually using the CLI.
For more information on what data gets collected, see VMware vSphere Solution in vRealize Operations Cloud.
You can manually upgrade your cloud proxy Using the Cloud Proxy Command-Line Interface on Cloud.
