A company stores customer data in a multitenant Amazon S3 bucket. Each customer's data is stored in a prefix that is unique to the customer. The company needs to migrate data for specific customers to a new. dedicated S3 bucket that is in the same AWS Region as the source bucket. The company must preserve object metadata such as creation date and version IDs.
After the migration is finished, the company must delete the source data for the migrated customers from the original multitenant S3 bucket.

Correct Answer:
A, B, F
The combination of these solutions provides an efficient and automated way to migrate data while preserving metadata and ensuring cleanup:
Create a new S3 bucket with versioning enabled(Option A) to preserve object metadata like version IDs during migration.
UseS3 batch operations(Option B) to efficiently copy data from specific prefixes in the source bucket to the destination bucket, ensuring minimal overhead.
Use an S3 Lifecycle policy(Option F) to automatically delete the data from the source bucket after it has been migrated, reducing manual intervention.
Option C (CopyObject API): This approach would require more manual scripting and effort.
Option D (Same-Region Replication): SRR is designed for ongoing replication, not for one-time migrations.
Option E (DataSync): DataSync adds more complexity than necessary for this task.
