 When rotating keys it is often necessary for previous keys to stay around for a time to decrypt past data. A previous key should never be used to encrypt data once it is no longer the primary key. It should only be used to decrypt the data it was used to encrypt. When the data is ready to be stored again it should then be encrypted with the current key and stored.
