Life cycle rules on S3 for existing items

Question

I have made a life cycle rule on my existing S3 buckets that put objects older than 60 days in Glacier Instant Retrieval. How can I apply this rule to items already in my bucket? Looks like it won't trigger for existing items.

Answer

The rule will be applied to existing objects but there are some limitations. See: [Supported transitions and related constraints
](https://docs.aws.amazon.com/AmazonS3/latest/userguide/lifecycle-transition-general-considerations.html#lifecycle-general-considerations-transition-sc). For instance:

```
Objects smaller than 128 KB – For the following transitions, Amazon S3 does not transition objects that are smaller than 128 KB:
* From the S3 Standard or S3 Standard-IA storage classes to S3 Intelligent-Tiering or S3 Glacier Instant Retrieval.
* From the S3 Standard storage class to S3 Standard-IA or S3 One Zone-IA.
```
