Can I change Ignition's OPC UA port

Ignition

Ignition 7.9 used port 4096 for its OPC-UA Server and Loopback connection. This was changed to 62541 in 8.1. I believe if you upgrade from 7.9 to 8.1, the port stays the same (if I read the documentation correctly). Is there a config file or setting that can allow me to specify the port number? I have found all the other port settings in the ignition.conf and gateway.xml files.

During a project upgrade, I was able to run older and newer Ignition instances on the same machine without problems (after making the necessary port and service changes). However, now I am running newer 8.1 Ignition and Edge on the same machine and the Edge can't bind to the OPC UA Server since the other instance is already bound to it. Do I have to install 7.9, then upgrade to 8.1 to have 2 different ports available?

It's the "Bind Port" on the OPC UA Server Settings page in the Gateway.

Right, I changed that to simply 62542 and restarted the gateway...no dice. Maybe I need to do a full reboot of PC?

Define what you mean by no dice? If you're trying to access it externally, make sure your binding IP address is 0.0.0.0 also. When you do change your port, you'll also have to reconfigure your OPC client to point to the new endpoint.

Oh, nevermind...over at the Server Settings page...found it. SMH. I kept on trying to edit the Endpoint URL and Discovery URL.
