Data Migration from One account s3 to another account s3 using data sync

Hi Raj

Moving data from one s3 bucket to another, your network bandwidth won't come into the play. Refer this Datasync Network Requirement.

However if you are migrating data from on prem to AWS, then you can control the bandwidth limit. Reference document link is here Datasync Limiting Bandwidth.

For pricing, datasync has fairly simple pricing and refer example3 here at this documentation Datasync Pricing . Though there are few other factors involved, but major one to keep in mind while using datasync is source and target region when both are AWS.

I'm pasting the verbiage for your quick reference from above mentioned link:

Copying data to and from Amazon S3

When copying data to or from S3, you are charged standard request charges for the following S3 requests: LIST, HEAD, GET, PUT, and COPY. The exact operations performed depend upon the configuration of your DataSync task. For more information, read about evaluating S3 request costs in our documentation. Requests and storage charges can vary between S3 storage classes. You may also incur additional charges when reading and writing objects in different S3 storage classes. Read about working with Amazon S3 storage classes in our documentation.

PS: S3 batch replication is something too, which can be considered for large volume of data transfers between two s3 buckets. S3 Batch Replication
