When attempting an upgrade of the ECC, the .war package does not unpack the full listing of files within the config folder. After attempting execution, you receive the following error:
FAIL - Application at context path <ECCPATH> could not be started.
The previous installation of your ECC system is interfering with the installation of the upgrade.
Perform the following steps:
1.) Backup your current installation for all configuration files.
2.) Enter into the Tomcat Manager (default <tomcat path>/manager/html).
3.) Undeploy any instances of the ECC ( Display Name - Automic Enterprise Control Center).
4.) Using the Tomcat Manager, deploy the new .war file.
5.) Update the new system with your previous configuration
6.) Start the new system within the Tomcat Manager
