We are replacing our Core L3 switch, but we would like to keep the DHCP bindings, so it will be less of a disruption. Is it possible to export the current bindings from the old switch and import them into the new?

HiYou can use the command ip dhcp database command to store all binding on a tftp or ftp drive.Then if you configure the dhcpn pool on both switches, you'll avoid ip conflict.
Here a documentation you can read:
