This tutorial describes how to migrate data from an Amazon Simple Storage Service (Amazon S3) bucket to an Alibaba Cloud Object Storage Service (OSS) bucket.
To migrate data from an Amazon S3 bucket to an Alibaba Cloud OSS bucket over an Express Connect circuit, see Overview.
Overview
The Alibaba Cloud Online Migration Service is a data transport service that helps you migrate data to OSS from third-party sources or between OSS buckets.
To use the Online Migration Service, enter the source and destination addresses in the console to create a migration task. Once the task starts, you can manage it, monitor its progress, and view traffic information from the console.
