Set S3 Glacier vault's storage class

Amazon S3 Glacier vaults can only be stored in a single Storage Class for a cost of $0.0036 per GB/Month in the N. Virginia region.

For an enhanced Amazon S3 Glacier experience, you can use the Amazon Simple Storage Service (S3) console instead of the Amazon S3 Glacier service. Accessing and using the Amazon Simple Storage Service (S3) Glacier storage classes through the Amazon S3 APIs and Amazon S3 console provides enhanced functionality for data management and cost optimization. This is where you can find Deep Archive storage class.

For more information about Amazon S3 Storage Classes, please refer to the following links:

You would have to download all your data from your Amazon S3 Glacier vault and then upload the data to an Amazon S3 bucket. You can use an EC2 instance with a S3 VPC Endpoint to eliminate any out-of-region data transfer charges. You can configure the data to be stored in the Deep Archive storage class during the upload using parameters in your SDK or CLI request. You can also configure the data to be moved to the Deep Archive storage class after being uploaded via a Lifecycle Policy or the S3 Console.
