Ignition 7.9 to 8.1 Upgrade Guide - UDT Parameter Usage Question

Hey everyone,

I’ve been testing an upgrade from 7.9 to 8.1.
In the upgrade guide (UDT Parameter Usage) it claims that parameter references will be updated upon upgrade

All existing references will be upgraded automatically to the new syntax upon system upgrade. Designers should be aware of this change when creating new Tags.

I assumed the UDT expression bindings I have setup on our alarms Custom Subject / Custom Message properties would be updated, but it seems like that’s not the case. All of them are unchanged after the upgrade to 8.1

Is that portion of the Upgrade Guide incorrect or am I simply misunderstanding what it is referring to?
