PnP - Editing provisioned device configuration

Question regarding the utilization of PnP with APIC-EM. Able to connect a router to APIC-EM, the device gets its configuration and is in provisioned state. So all good.

However, cannot make a change to the configuration file, or push a new config file to the provisioned device. The GUI doesn't let me edit the device and generates the message: "Some of the selected devices cannot be edited in their current state! ".

That is correct -- that is the expected behavior. PnP only allows to push configurations to unclaimed devices.Once the devices are configured by PnP, they are considered to be provisioned, thus you cannot push any new configurations.

You can try to delete the device from the PnP app and have it call home again. When the device calls home again, it will be considered unclaimed again and you can push new configurations to the device.  This is considered a hack and not how the app is intended to be used.
