Upgrading agent relays#

When you upgrade the server, be sure to always upgrade agents and agent relays.

Upgrade the server.

The CodeStation request port is configured automatically on the system where the agent relay is located. The CodeStation port number is one greater than the number assigned for HTTP communication. By default, the HTTP port is 20080. If you use the default value for the HTTP port, the CodeStation request port would be numbered 20081.

If the CodeStation request port is blocked, agents cannot download artifacts. If you upgrade from versions before 6.1, ensure that the port is not blocked by the firewall or other processes on the agent relay system.

Important: Beginning in version 6.2.2, the HCL™ Launch server and agent relays require a Java™ Runtime Environment (JRE) or Java Development Kit (JDK) version 8.

Important: After you upgrade to HCL UrbanCode Deploy version 6.2.2 or later, note these changes to agent relays:
