How to reencrypt SageMaker domain with a new KMS key?

Question

Hi, my current domain was created using a previous KMS key. Now I want to retire the key and use a new key. How should I proceed?

Answer

Hello there,

When you create a domain with a ``KmsKeyId`` specified [1]: AWS SageMaker uses the KMS key to encrypt the EFS volume attached to the domain. 
As mentioned from AWS EFS documentation [2], after an EFS file system has been created, its encryption settings cannot be altered. As such you cannot change the KMS Key of an existing EFS file system.
