Is it possible to import tag groups, say from 7.9 scan classes in an upgrade process. If it’s not possible, could this be added as a feature?
Yeah, we’ll definitely make sure to get this handled soon. Tag groups should be exportable/importable as before, and should accept the scan class definition for upgrade.
This issue was fixed in the build uploaded today (4/10).
Normally we have the nightly builds accessible via https://inductiveautomation.com/downloads/ignition, but in the meantime you can find it via this post:

Let us know if you have any issues.
I’m not sure the issue is relative to import only, or tag restart but sometimes blank tag group are added and Default and Default historian tag group disappear from the list.
