These enhancements allow you to move your existing SFTP servers with multiple host keys and host key types to AWS Transfer Family. You will also be able to add and tag host keys before rotating them, giving you more control over your managed file transfer environments.
Multiple host keys and host key types are supported in all Regions where AWS Transfer Family is available. You can configure server host keys using the AWS Management Console, AWS Transfer Family API, or AWS Command Line Interface (CLI).
