This section documents the process of migrating end devices from V2 to The Things Stack.

Prerequisites

1. User account on The Things Network V2 or The Things Industries V2.
2. End device(s) and gateway(s) connected to a V2 network.
3. User account in The Things Stack.

Add Application in The Things Stack

Since end devices are being created within applications, you first need to add a new application in The Things Stack.

See Adding Applications for detailed instructions.

Add Payload Formatters and Integrations in The Things Stack

After creating an application, you need to add the associated elements like application-level payload formatters and integrations.

function Decoder(bytes) {
    var temperature = bytes[0] | bytes[2];  
    return {
        temperature: temperature;
    }
}

function decodeUplink(input) {
    var bytes = input.bytes;
    var temperature = bytes[0] | bytes[2];
    return {
        temperature: temperature;
    }
}

See Payload Formatters guide for detailed instructions on how to add payload formatters and which types are supported by The Things Stack.

For detailed tutorials on the integrations that are available in The Things Stack, see Integrations.

Migrate End Devices

When you have added your application and elements associated with it, it is time to migrate your end device(s) from V2 to The Things Stack.

There are two approaches for migrating devices, depending on how many end devices you intend to migrate and if you wish to migrate with or without active sessions, described in the following guides:

• Using The Things Stack Console
• Using ttn-lw-migrate tool
