When I upgraded a 7.9 project to 8.0.0 none of my tags worked. I looked and the reason was that the Ignition OPC server name had changed from “Ignition OPC-UA Server” to “Ignition OPC UA Server” (no hyphen). I exported the XML, removed the hyphen, re-imported and the tags are working again.
Why !!! Anyone else see this issue ?
Note: my process for upgrading involved creating an empty project in a brand new gateway and directly importing my tags (I was trying to fix other issues that prevented upgrading from 7.9.10)
