I am currently having a IG 3.7 in Production. I am planning ro upgrade to 3.7.3.
There is a Component Upgrade Script to compare and update the Tomcat, Java and ActiveMQ components which are fine.
However, in the IG 3.7.3 software, there is only IG and OSP Installer which I try to run, and it doesn't recognise existing installation and recommend to upgrade.
To me it's like performing the installation to overwrite existing installation.
Am I missing anything or there is a upgrade switch or similar upgrade script available ? The Documentation doesn't help much in this....
