CloudLink upgrade overview Upgrading CloudLink involves uploading the upgrade ISO file and initiating the upgrade. All servers in a CloudLink Center cluster are automatically upgraded during the upgrade process. Connected CloudLink Agents are automatically upgraded if the Machine Agent Upgrade policy is set to Auto. Any CloudLink Agent that is not connected is automatically upgraded the next time it connects to CloudLink Center. CloudLink enables you to manually upgrade CloudLink Agents after you upgrade CloudLink Center or a CloudLink Center cluster, if the Machine Agent Upgrade policy is set to Manual.
