After upgrading LiveUpdate Administrator (LUA) to a new version, customized port configurations for the Apache Tomcat and PostgreSQL services revert to their defaults.
The migration script for LUA does not carry over port customizations from the original install.
This problem is fixed in the installer for LUA 2.3.6. Migrations to 2.3.6 or higher will honor customized non-default ports for LUA services. Read Download LiveUpdate Administrator for more information on obtaining the latest version of LUA.
