S3 Migration Between AWS Accounts: Pain or Triumph?

A real-world case study of migrating petabytes between AWS accounts: unexpected pitfalls and how we overcame them with hybrid approaches.

Читать на русском

BI

Today I reviewed a client case involving migration of multiple petabytes between AWS accounts. On paper — S3 cross-account copies, what could go wrong? Turns out, everything.

Where's the catch?

Key pitfalls:

  • IAM policies on source buckets don't carry over
  • Object Lock requires special handling
  • Transfer Acceleration can spike costs without proper rate limits

    • What saved the day

      A hybrid approach worked:

      1. Initial snapshot via Storage Gateway
      3. Delta sync using S3 Batch Operations
      5. Final validation with Athena checksums

        6. Has anyone faced similar challenges? How did you handle large-scale cross-account migrations?
