You can delete an encryption key from a file on the HDvM - SN computer or from a key management server (KMS) under the following conditions:
- When you change the location in which encryption keys are created from the storage system to a KMS in the Edit Encryption Environmental Settings window.
- When you migrate the KMS to a different server and use a newly created encryption key instead of the previously created encryption key.
After deleting encryption keys, you should create the maximum number of encryption keys that you can create.
