2.1 Upgrading a PEM Agent

To upgrade a system that is currently monitored by a PEM agent to a more-recent version of PEM agent, simply download and invoke a newer version of the platform-specific PEM agent installer on the system that the agent is monitoring.

If you are a Linux user, you can invoke the installer by opening a terminal window, assuming superuser privileges, navigating to the directory in which the installer resides and entering:

./pem_agent-x.x.x-linux.run

Where x.x.x specifies the version information for the installer.

If you are a Windows user, you can invoke the installer by right-clicking on the downloaded installer's icon, and selecting Run as Administrator.
