Hi, Ellen-- This might not work for you--we're a special library with very low circulation and don't pull any important reports on new items--but in similar circumstances, where we do have an item that's circulated a lot and been replaced with a better copy, I've simply edited the existing item record to put in the new barcode, and put in a non-public note into the item record with, e.g., "damaged item replaced with new item Mar. 17, 2017." I also make sure the other fields are correct, if, for example, our patron supplied the replacement copy, or it had been marked "Damaged," etc. This method does not affect the date acquired field at all, and really is fudging things quite a bit, so please do think about it with caution!
