+This section contains instructions on how to configure migration tool and use it to convert end device information exported from [Kerlink's Wanesy Management Center](https://www.kerlink.com/), into {{% tts %}} end device format.
+
+<!--more-->
+
+### Before you begin
+
+Reach out to Kerlink for a CSV file that contains exported device data. The following is an example.
+
+```csv
+devEui,clusterId,clusterName,name,classType,rfRegion,country,macVersion,regParamsRevision,profile,adrEnabled,activation,appEui,appKey,fcntDown,fcntUp,devNonceCounter,fNwkSIntKey,sNwkSIntKey,rx1Delay,rx1DrOffset,rx2Dr,rx2Freq,rxWindows,cfList,dwellTime,pingSlotDr,pingSlotFreq,geolocation,latitude,longitude,altitude,status,lastDataUpMessage,lastDataDownMessage,lastDataUpDr,device_profile,dev_addr,NwkSKey,AppSKey
+1111111111111111,0001,Test,Test,A,EU868,,1.0.2,A,STATIC,True,OTAA,1111111111111111,22222222222222222222222222222222,10,20,False,,,,,,,,,,,,,,,,,,,SF7BW125,,1234567,33333333333333333333333333333333,44444444444444444444444444444444
+```
+
+- The export process will halt if any error occurs.
+- Since the migration tool uses a CSV file that's exported from WMC and does not interact with the API, make sure to remove/clean up the devices on WMC once the migration is completed.
+
+### Configuration
+
+Configure with environment variables, or command-line arguments.
+
+See `ttn-lw-migrate wanesy {device|application} --help` for more details.
+
+The following example shows how to set options via environment variables.
+
+```bash
+$ export APP_ID=my-test-app             # Application ID for the exported devices
+$ export FREQUENCY_PLAN_ID=EU_863_870   # Frequency Plan ID for the exported devices
+$ export CSV_PATH=<path>                # Local path to the exported CSV file.
+```
+
+The above settings are common for all the following export methods.
+
+### Export Devices
+
+{{< tabs/container "Single device" "Multiple devices" "All devices" >}}
+
+{{< tabs/tab "Single device" >}}
+
+To export a single device using its Device EUI (e.g. `1111111111111112`):
+
+```bash
+# Export a device from the CSV to TTS format.
+$ ttn-lw-migrate wanesy device 1111111111111112 > devices.json
+```
+
+{{< /tabs/tab >}}
+
+{{< tabs/tab "Multiple devices" >}}
+
+In order to multiple devices, create a file named `device_euis.txt` with one device EUI per line:
+
+```txt
+1111111111111112
+FF11111111111134
+ABCD111111111100
+```
+
+And then export with:
+
+```bash
+# Export multiple devices from the CSV.
+$ ttn-lw-migrate wanesy device < device_ids.txt
+```
+
+{{< /tabs/tab >}}
+
+{{< tabs/tab "All devices" >}}
+
+In order to export all devices from the CSV file, use the `application` command.
+
+```bash
+# Export all devices from the CSV.
+$ ttn-lw-migrate wanesy application --all
+```
+
+{{< /tabs/tab >}}
+
+{{< /tabs/container >}}
+
+After exporting, devices can be imported in {{% tts %}}. See [add end devices in bulk in {{% tts %}}]({{< ref "/devices/adding-devices/adding-devices-in-bulk" >}}) for details about importing devices.
