IS it possible to back up an application+end device configurations?

[ScottPorter]

Hi, as per the title, is there an option somewhere to download the setup for an application in the TTN backend, along with the payload formatters and end devices, so that it can be restored or copied to another application?

Also, can the DevEui and AppKey be re-used? I.e. if I remove an end device from an application, and want to move it to another without updating AppKey device itself, could I copy these params across to the new application so it continues accepting data?

Thanks.

Yes you can reuse a DevEUI and AppKey. However you will only receive data in the new application if:

1. The AppEUI Is the same again
2. The device rejoins. It needs to establish a new set of session credentials (session keys and device address) in the new application which requires a join operation.

For the backup option you could look at what the CLI provides.

That’s great, thank you!
