示例2：创建数据迁移任务
场景描述
本章节指导用户通过API创建数据迁移任务。API的调用方法请参见如何调用API。
本文使用在线迁移、全量迁移的方式为例创建数据迁移任务，源实例与目标实例是华为云上处于相同VPC的Redis。
步骤1：确定源实例的IP和端口
- 查询指定实例的IP和端口。
- 接口相关信息
- 调试
您可以在API Explorer中调试该接口。
- 请求示例
GET https://{dcs_endpoint}/v2/666486c2d9b948c1bbea57e714d744fa/instances/21bc7b53-2494-4f10-bb0b-c0b913d9e329
{dcs_endpoint}信息请从地区和终端节点获取。
- 响应示例

- 根据需要，记录实例的IP和端口。
步骤2：创建数据迁移任务
- 接口相关信息
- 调试
您可以在API Explorer中调试该接口。
- 请求示例
