400108 error on migrating the data

var config = {
      method: 'post',
      url: 'https://api-{MY-APP-ID}.sendbird.com/v3/migration/18374',
      headers: {
        'Content-Type': 'application/json',
        'API-Token': {MY-API-TOKEN},
      },
      data : {
        "messages":data,
        "update_read_ts":false
      }
    };

    axios(config)
    .then(function (response) {
      console.log(JSON.stringify(response.data));
    })
    .catch(function (error) {
      console.log(error);
    });

I am trying to migrate my old data to use sendbird now.
While trying to migrate in a format that sendbird doc says, I faced an error saying that
data: {
message: ‘Not authorized. “Migration is not allowed.”.’,
code: 400108,
error: true
}

Any helps can I get?

Hi @JuyeongLee,

Welcome to the Sendbird Community!

I have a couple of quick questions for you. If you could respond to them in a DM to me:

  1. How much data are you looking to migrate? How many users, messages etc.
  2. What is your Application ID?

i got same problem. did you resolved it?
