This tutorial describes how to migrate data between Alibaba Cloud Object Storage Service (OSS) buckets that are owned by multiple accounts or deployed in the same or multiple regions.

Alibaba Cloud Data Online Migration is a data channel between different storage services. You can use Data Online Migration to migrate data from third-party data stores to OSS or between OSS buckets.

When you use Data Online Migration, you need only to log on to the console, specify a source data address and a destination OSS data address, and then create a migration job. After the migration job starts, you can manage the job in the console. For example, you can view the progress and traffic information of the job. You can also generate a migration report to check the list of migrated files and the list of files that fail to be migrated.

Notice
  • When you read data from the source data address during a migration job, a fee is incurred for the outbound Internet traffic. You are charged by the storage service provider of the source data address.
  • By default, Data Online Migration does not support cross-border data migration. For example, you cannot migrate data from a bucket that is deployed in the China (Beijing) region to a bucket that is deployed in the US (Silicon Valley) region. Before you create a migration job to migrate data across borders, you must submit a ticket to apply for the permissions that are required for creating cross-border migration jobs. You must commit that your business is legitimate, data transit conforms to local rules and regulations, and your data does not contain illegal information.
  • You cannot migrate data between OSS buckets if the data at the source data address is stored in a bucket of the Archive type.
