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)

Bleh, it was changed along with all other references to “OPC-UA”. Didn’t think it would be a big deal because most people should be doing upgrades instead of importing things piecemeal from 7.9, and it’s a simple find/replace before the import if you are.
What were those issues? Have you already posted here/contacted support about them?
I just came across this issue as well.
I had a script developed on Ignition 8.0 that referenced “Ignition OPC UA Server” (no dash between “OPC” and “UA”) to make an OPC read call to a tag.
I moved the project and script to a server that was 7.9 at one point, but is 8.0.x now, and the internal server is “Ignition OPC-UA Server” (has a dash). This broke the script.
I’ll have to see if anything else references “Ignition OPC-UA Server” (with a dash), but is the recommendation to rename the server to remove the dash on these systems to bring them in-line with the newer versions?
We don’t recommend one way or the other, do whatever is going to work for you. The name is just a default and carries no additional meaning and isn’t hard coded anywhere in the platform. The loop back connection gets no special treatment compared to other connections.
So, I would like to rename the server back to having the dash. Version 8.1.23 how to do it? I was not able to find any place to change the name in the configuration pages.
with more Googling, I found it. It is here:
On the Configure page of the Gateway, go to OPC Connections > Servers.
The OPC Server Connections page is displayed.
I was stuck thinking it would be on the server setting page.
My need is to keep 2 copies of a project the same on 2 different gateways.
If I need cross-compatibility in a dev environment, I just make two loopback connections. One with, one without the dash.
