I’m trying to migrate devices from V2 to V3
first of all I copied device app/device/and key from V2 to V3 and then changed key on V2 so device won’t be able to join on V2. device reset but never joined V3
So I decided to follow official documentation tutorial for about 2H and it still not working so I put back my device in V2, device is seen (on V2) and sending data so let’s explain an reproduce the issue in case someone will be able to help.
I’m using latest ttn-lw-migrate as today, and since community stack is below V3.12 I prepared as stated here with
--ttnv2.with-session=false
But note this is not in sync with tutorial that state that if backend version is 3.10 or higher we can migrate keeping session.
So here we go (I masked keys by * all below)
./ttn-lw-migrate devices --ttnv2.with-session=false --source ttnv2 "mercury-16" >mercury16.json
INFO Clearing device keys dev_eui=****** device_id=mercury-16
now looks into JSON file (I pretty printed for easier reading)

now use import tool v0.4.0-rc1, the application is already created and already have some devices working
./ttn-lw-cli end-devices create --application-id "enviro-dev" < mercury16.json
error:pkg/ttnpb:parse (could not parse `{"value":6}` into `ADRAckLimitExponent`)
field=ADRAckLimitExponent
value={"value":6}
--- strconv.ParseInt: parsing "{\"value\":6}": invalid syntax
Looks like export/import are not in sync I even tried old export v0.2.0-rc2 without any success
What step did I missed?
