!!! warning ## ACLs
Whilst it might seem counter-intuitive, a **pull**-based transfer is significantly simpler than a **push**-based transfer. Notably, it avoids [issues](https://stackoverflow.com/a/63804619) with ownership issues and ACLs.
Whilst it might seem counter-intuitive, a **pull**-based transfer is significantly simpler than a **push**-based transfer. Notably, it avoids [issues](https://stackoverflow.com/a/63804619) with ownership issues and ACLs. Bucket policies don't seem to apply if the object is owned by a different account, which is the case when ACLs are enabled and the object is written by a user not in the organisation (hence pull-based being best).
These can be solved by overwriting the file's ACLs to enforce the bucket owner owns the file: These can be solved by overwriting the file's ACLs to enforce the bucket owner owns the file:
``` ```
aws s3 cp --recursive 's3://<destination_bucket>` 's3://<destination_bucket>` --acl bucket-owner-full-control --metadata-directive REPLACE aws s3 cp --recursive 's3://<destination_bucket>` 's3://<destination_bucket>` --acl bucket-owner-full-control --metadata-directive REPLACE
``` ```
It's then good practice to make sure the ACLs are as you expect (eg [`./manage.py fix_document_acls`](https://github.com/torchbox/wagtail-storages?tab=readme-ov-file#django-admin-fix_document_acls)).
