Which of the following statements about migrating data into and out of Object Storage Service...

You can migrate data between OSS buckets in any of the following conditions: Buckets are located within the same region, buckets are located across regions and buckets belong to different Alibaba Cloud accounts.

A migration job occupies the network resources of the source and the destination. To ensure business continuity, we recommend that you specify a rate limit for a migration Job or run the migration job during an off-peak period.

Online migration supports both migrating buckets at a time, and migrating all the data under an Alibaba Cloud account at a single time.
