You can use PEM graphical installers to update a PEM agent or server that was installed with a graphical installer to a more-recent version. Links to PEM and SQL Profiler installers are available at the EnterpriseDB website at:To upgrade PEM component software, simply invoke a newer version of the PEM component installers in the following order:
1. Invoke the PEM agent installer on each monitored node except the PEM server node. Please note that your upgraded PEM 7.3 agents will work with the PEM 6 server while the upgrade is being performed.
2. Invoke the PEM server installer; this installer will upgrade both the PEM server and the PEM agent that resides on the PEM server node.During an installation, the component installer will automatically detect an existing installation, and perform an upgrade. After upgrading the PEM components, you should upgrade SQL Profiler; this step is platform-specific.As of PEM 7, the PEM client interface is installed as part of the PEM server component, and is accessed with your choice of web browser. For detailed information about using the PEM 7 web interface, please see the PEM Getting Started Guide.Please note that if you have used an RPM package to install your server or agent, you must use an RPM package to upgrade the installation. Likewise, if you initially installed with a graphical installer, you must upgrade with a graphical installer.
