+After the code is updated, you need run `terraform init -upgrade` to download newer AWS provider, and then import S3 bucket ACL using such command:
+
+```
+terraform import "module.s3_bucket.aws_s3_bucket_acl.this[0]" my-awesome-bucket,log-delivery-write
+```
+
+Where `log-delivery-write` is the value of `acl` argument in the module block above.

 #### Import existing resources (required during the migration from v2.x of this module)
 
 During the migration to v3.x of this module, several S3 resources will be created by this module. In order to guarantee the best experience and prevent data loss, you will need to import them into terraform state using commands like these:
 
 ```bash
 terraform import "module.s3_bucket.aws_s3_bucket.this[0]" <bucket-name>
+terraform import "module.s3_bucket.aws_s3_bucket_acl.this[0]" <bucket-name>,<acl>
