New version, same UPC: kit the carton
Tooling changed. The UPC did not. The live title still names last year’s insert, count, or material. If you receive the new version on the old page, every order is a bait-and-switch. The Transformation Kit is the check before that receive: pad from the new carton, then a rewrite or a new child.

Treat the new carton as a new product
Write type, size or count, material, and what is in the box from this inbound. Photo of the pad next to that pack. Compare it to the live title. If any of the four facts changed, the UPC is not a free pass. Same barcode, different box, is still a different listing job.
Either rewrite this ASIN or split a new child
If old units are gone, kit title and first bullet from this pad and save before the receive. Run free optimize only if the English still names the old version. If old units are still in FBA, do not dump the new version on top. You need a new child from this pad, or you wait until the old lot sells through and then kit again.
A reused UPC is not a reused listing
