Symptoms

When a vRealize Appliance has been configured as a dedicated standalone PostgreSQL database server you receive an error when attempting to upgrade the appliance to vRealize 6.2

The vRealize Automation services run on another vRealize Appliance that connects to the standalone PostgreSQL database server

Cause

This issue occurs because the upgrade runs a post-install script that requires the vRealize Appliance to be connected to a PostgreSQL database.

By default, when configuring a vRealize Appliance as a standalone PostgreSQL database you do not configure the appliance to connect to the local database. Additionally, configuring this connection on a standalone PostgreSQL database causes a configuration setting to change that prevents external connections such as those from the vRealize Appliances running the Automation services.

Resolution

Perform a backup of configuration files and snapshots of the vRealize Appliances prior to performing these steps.
