2 Upgrading a PEM Installation : 2.1 Upgrading a PEM Agent
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a system that is currently monitored by a PEM agent to a more-recent version of PEM agent, simply download and invoke a newer version of the platform-specific PEM agent installer on the system that the agent is monitoring.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.

2.2.1 Using an RPM Package to Upgrade the PEM Agent
You can use an RPM package to upgrade existing agents that were initially installed by a package. The upgrade process does not update the PEM agent configuration file. After installing the new agent, you must manually copy the configuration file of the existing agent to the new installation location.
To use RPM packages to upgrade a PEM agent, you must:
1.
Upgrade the installed version of the PEM agent:
yum upgrade pem-agent
2.
If upgrading from PEM 6.x, copy the configuration file to the location of the PEM 7.x configuration file (/usr/pem/agent/etc/agent.cfg). For example:
cp /usr/pem-6.0/etc/agent.cfg /usr/pem/agent/etc/agent.cfg
For detailed information about using an RPM package to install the PEM agent, please see the PEM Installation Guide or the Advanced Server Installation Guide, available at:
