Cloud Proxies are upgraded to a compatible cluster version automatically after the cluster upgrade. Expect a downtime of one or two cycles, as cloud proxies do not collect any data during this period. Data collection resumes after the upgrade is complete. The upgrade process runs concurrently for up to ten cloud proxies. If you have more than ten cloud proxies, the upgrade process will continue sequentially and the next cloud proxy upgrade will start as soon as any one of the ten running upgrades completes or fails the upgrade process. 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 the topic called "VMware vSphere Solution in vRealize Operations" in the VMware vRealize Operations Configuration Guide.
You can manually upgrade your cloud proxy Using the Cloud Proxy Command-Line Interface.
