Spectrum locked up for a couple minutes when I was moving 9 Network models from new Devices to Universe at the same time.
Release : Any
Component : Spectrum Discovery/Modeling
When a Topology model (Network or LAN for example)is cut and pasted into a new Topology, the Topology model that is cut and pasted along with the models container within the Topology model and their child models have a number of their current associations removes and then new associations created. There can be thousands of associations involved. If so, this can take time to complete.
Copy fewer models at the same time.
