Abstract: This document describes methods and systems by which a data storage service migrates a volume of stored data from an unencrypted format to an encrypted format while still permitting user access to the data. The encryption process uses migration markers to identify records that have undergone the encryption process. When migration is complete, the service removes the migration markers and retains the encrypted data in a data storage facility.
