You can update directly from Pillar Axiom Path Manager (APM) or from an earlier version of Oracle FS Path Manager (FSPM) to latest version of FSPM. You do not need to uninstall the previous version of APM or FSPM.
To update FSPM, follow the installation instructions in this guide for installing FSPM when it is not already installed. This installation automatically replaces the existing version, whether APM or FSPM to the version of FSPM you chose to install.
