8. A computer-implemented system comprising:
a storage; and
a processor that runs a tenant host and determines, a first Key Management Service (KMS) indicated as storing a cryptographic key associated with the tenant host from a new KMS mapping,
sends to the first KMS a request for the cryptographic key associated with the tenant host,
receives an indication from the first KMS that the first KMS does not store the cryptographic key associated with the tenant host,
determines a second KMS indicated as storing the cryptographic key associated with the tenant host from an original KMS mapping,
receives from the second KMS the cryptographic key associated with the tenant host, and
sends to the second KMS a request that the cryptographic key associated with the tenant host be replicated from the second KMS to the first KMS.
