Introduction

This guide describes what steps have to be taken when a customer wants to install Site Controller Version 1.3 on a running system, which is already connected to the azeti Engine. There is no automatic upgrade for version 1.2 to 1.3. Instead the customer has to do a fresh installation and migrate the existing configuration, as there have been structural changes in 1.3 that avoid an automatic approach. This guide explains the steps necessary and gives some guidelines on things to keep in mind.

Major Changes

Some of the major changes in 1.3.0 include:

  • The file azeti_logging.cfg is obsolete. All logging-related settings are now integrated into SiteController.cfg

  • As a result SiteController.cfg is not compatible between 1.2 and 1.3 - hence a real upgrade is not possible

  • Modules can be defined to autostart in SiteController.cfg or the SensorConfig
  • A new major module is the data_store. This module now takes over the tasks of hd2cloud exporter & cloud connector
  • Status-Command of Site Controller does now include the status of the connection to the external broker and port used / configured
  • Various bugfixes and improved stability 
    • data_store is able to repair a single DB-corruption (Please note: second DB-corruption will break the Site Controller and a manual restart is mandatory)
    • XML-parsing is more robust

Abstract

This guide describes how to remove the currently installed Site Controller in version 1.2 and do a fresh install with the version 1.3 of the Site Controller. After the new version has been installed, the customer will re-apply custom changes from the old installation. An automated approach has not yet been tested to a statisfactory result, therefore the manual approach has to be taken.
