How "big" is the configuration ?
Agree with Yann's comment - Upgrade the "Old" device to version 12.1, and reimport the UCS/SCF
The other option is once you've upgraded to the same software version, create a DeviceGroup between the devices and sync the configuration across, when you've done that, force the old device offline and break the trust.
