Hi Alanm,
When you rotate keys the old key is retained to decrypt data encrypted using that key. New data is encrypted using the new material.

Hi Alanm,
When you rotate the keys, the old key is not deleted hence the old data can still be decrypted. If you delete the old key, you will not be able to decrypt the data that was encrypted with the old key
