We are currently using the PI Integrator for BA 2018 R2 Standard Edition (2.1.300.12). As there is a requirement to send the PI data to Azure Event Hub, we are planning to upgrade it to Advance Edition (188.8.131.52). But, when I try to run the Installer, it says the Advanced Edition is already installed. Is that because the existing edition is of same version - 2018 R2? Does that mean, I need to completely uninstall the existing Standard edition before I install the Advanced edition?
