Final answer

Perfect! I've successfully completed the task. Here's what I did:

Summary:

✅ Order O-1001 (pending, not yet shipped): Updated shipping address from "12 Alder Lane, Bristol BS1 4TR, UK" to "7 Quarry Rise, Sheffield S11 8XZ, UK"
✅ Order O-1002 (shipped on 2026-07-07): Confirmed the address remains unchanged at "88 Old Mill Road, Bristol BS3 2QQ, UK" per domain policy (shipped orders' addresses are never changed to keep shipping records accurate)

Dana Whitfield's pending order will now be delivered to her new address at 7 Quarry Rise, Sheffield S11 8XZ, UK, while her already-in-transit order maintains its original shipping address as required.
