Replace a Device with the Same Configuration

You can replace a device that has the same configuration as the new device without affecting the network or the configuration.

Ensure that the configuration from the old device is copied to the new device.
Ensure that the device information in EFA is current.
Do not perform this step if all configuration changes to the device are done through EFA.
```
efa inventory device update ip –<IP address of the old device>
```
Note
- This command ensures that the Asset service has the latest information.
- If the replaced device is not reachable or responding and the configuration being copied to the replacement device does not match the details in the Asset service, see Replace a Device with a Different Configuration.

Replace the device.

efa inventory device replace ip -<IP address of the new device>

Example

This example shows typical output for a successful device replacement.

efa inventory device replace ip -10.x.x.x
