Further, since the configuration data is encrypted with the KMS, the KMS
configuration itself can no longer be stored in the MinIO config file and
instead must be provided via environment variables. If you have set your KMS
configuration using e.g. the `mc admin config` commands you will need to adjust
your deployment.
