I notice that the 2019 PI Vision Display Utility expects the source and destination PI Vision Server applications to be both available on the same network in order to copy displays from one to the other. This is fine if the system includes a prod/dev architecture. But of no use when working offline on a PI-Dev system, when in a project environment you typically would develop displays and then export to the target.
The method used in 2017 R2 was better in that all you had to do was drop the SQL database from your dev system, connect it to the target SQL Server instance and then the display utility migrated the displays at the database level just by being able to connect to both databases.
Is it possible to move displays from a PI-Dev -> End User system without having both PI Vision servers on the same network?
