Hi,

I am encountering an issue when exporting and importing tags between Tag Providers on the same Gateway.

Scenario:

- Ignition version: 8.1.52

- Same Gateway (Export/Import so both tag provider access same device)

- Exported from one Tag Provider and imported into another for demo/testing purposes

Export contents:

- Tag Group(s), UDT Definitions, Tags

Steps performed:

1. Exported Tag Groups, UDTs, and Tags from the source Tag Provider.

2. Imported them into the target Tag Provider in the following order: Tag Groups, UDT Definitions, Tags

Issue observed:  
After the import, none of the OPC tags subscribe or update. No OPC values come through. Additional observations:

- If I change the affected tags to use a _newly created_ Tag Group, they immediately begin working!!!

- If I delete the imported Tag Group and recreate it with the same name, the tags still do not work.

- This suggests the tags may be referencing an internal Tag Group identifier that is no longer valid after import.

Expected behavior:  
Imported tags should correctly bind to the imported Tag Group (or rebind by name), and OPC subscriptions should function without requiring manual reassignment.

Could anyone confirm whether this is a known issue in 8.1.x, and if there is a recommended or supported workflow for moving tags between Tag Providers on the same Gateway?

Hmm. I haven't heard this one. You should open a support ticket.
