Upgrading the Cloud Agent

You can use the Qualys Cloud Platform to upgrade your Cloud Agent to the latest available version. To upgrade, Cloud Agent must be connected to the Qualys Cloud Platform and must have auto-upgrade permission in the configuration profile. 

If a Cloud Agent is not configured for auto-upgrade, the software distribution tools can package an installer of the latest version, and the new version is not installed.

The Windows Cloud Agent installer supports a command line argument ("PatchInstall") that enables an upgrade in place of the installed agent. This retains the agent UUID, Customer ID, and Activation Key configuration of the Cloud Agent on the agent host.

 It is required for software distribution tools to use a specific command line argument to upgrade existing installed Windows agents. If the specific command line argument is not used, the installer fails to upgrade the existing installed Windows Agent.

For exe based installer:

QualysCloudAgent.exe PatchInstall=TRUE

For MSI based installer:

Msiexec.exe /i CloudAgent_x86.msi Patchinstall=true

Do not append the Customer ID or Activation Key arguments, while using the patchinstall argument.

Cloud Agent Self-Patching

The Cloud Agent automatically upgrades through self-patching. For successful self-patching the Cloud Agent needs access to the following Revocation servers. These servers enable the agent host to receive the public root certificate used to sign the agent binaries:

http://ctldl.windowsupdate.com/
http://rb.symcd.com/
http://rb.symcb.com/

 This is required only for agents upgrading from 2.0.2 - 2.0.6 to 2.1.x.
