The old OS won't run on a new Pi 3B+ without an update. You need to update some of the boot files on the SD card. I thought that Buster was updated to support those, but it's possible it wasn't.
Look at this link https://pip.raspberrypi.com/categories/ ... rmware.pdf and read the second section for Updating the Firmware Manually. Follwo that procedure and hopefully your cards will boot in the newer Pi.
