Abstract
Generally described, one or more aspects of the present application correspond to techniques for modifying volume encryption status, either by creating an encrypted copy of an unencrypted source volume or by re-encrypting the replica with a different key than the source volume. This can be accomplished using an intermediary transform fleet that stores the encryption key(s) and performs encryption (and decryption, in cases where the source is encrypted). Further, these techniques can implement a state refresh for any client attached to the volume in order to equip the client to handle the different encryption state of the encrypted volume.
