Creating a Migration Task

Scenarios

This section describes how to create a migration task by calling APIs. For details, see Calling APIs.

Involved APIs

Obtaining a User Token Through Password Authentication: This API is used to obtain a user token for authentication.
Registering a Source Server with SMS: This API is used to register a source server with SMS.
Creating a Migration Task: This API is used to create a migration task using a target AK/SK pair.
Querying a Migration Task: This API is used to query the details of a migration task with a specified ID to check whether the migration task is successfully created.

Prerequisites

You have obtained an AK/SK pair for accessing the target platform. For details about how to obtain an AK/SK pair, see Where Can I Obtain Access Keys (AK and SK)?

Procedure

Obtain an IAM user token.

API
URI format: POST /v3/auth/tokens

For details, see Obtaining a User Token Through Password Authentication.

Example request

POST: https://{iam_endpoint}/v3/auth/tokens

Obtain {endpoint} from Regions and Endpoints.

Body:

{
    "auth": {
        "identity": {
            "methods": [
                "password"
            ],
            "password": {
                "user": {
                    "name": "username",
                    "domain": {
                        "name": "domainname"
                    },
                    "password": "******"
                }
            }
        },
        "scope": {
            "project": {
                "id": "0215ef11e49d4743be23dd97a1561xxx"
            }
        }
    }
}

In the response header, the value of X-Subject-Token is the token.

X-Subject-Token:MIIDkgYJKoZIhvcNAQcCoIIDgzCCA38CAQExDTALBglghkgBZQMEAgEwgXXXXX...

Report the source server information and register the source server.
