We recently upgraded alot of CE500 and ESW520 Switches to Cisco Catalyst switches.
We thought a rediscovery would update the model for us but this was not the case.
I opened a ticket with tech support and they told me since the interfaces were different the devices would not update.
I had to delete the old device and add the new device.
Suggestion: there sould be a option in rediscovery to allow user the option to update new device information.
Also if a device information has changed deplayed a warning bulletin at the top of the page
