After enabling internal encryption, you can switch from internal encryption to an EKM. - If internal encryption was enabled at installation, you can switch from internal encryption to an EKM. - You cannot switch between EKM types. When encryption is enabled on the cluster, every tenant created on the cluster must be associated with an encryption group. This can be a new or a pre-existing encryption group.
