The Pentaho Data Integration utility (PDI) is not available in the v14.5 deployment of Virtual Appliance.
IGA 14.5
Starting from the Identity Governance 14.5 release, Broadcom is no longer shipping Pentaho Data Integration (PDI). However, Identity Governance continues to ship the required custom plugins. In a fresh Identity Governance deployment, you must manually download the supported PDI version (9.3.0) from its official website and place the shipped custom plugins in the downloaded PDI package.
