Re-identifying a device
Changing the device ID in the system is different from changing the device name. If you change
the ID, you must associate existing performance data with the new device ID; otherwise, you lose the
data for this device. However, the re-association process takes time, and during processing, metrics are
not collected or graphed for this device.
You have the option of deleting existing performance data and starting fresh with the new device ID. Collection of new performance data begins immediately.
