I second what others have said - crap.
But there could be some hope, not sure.
Can you check what is the actual size used by the pool on the disk?
It should be somewhere in zdb -C output ("asize"?).
If I remember correctly, that actual size should be a multiple of some rather
large power of two, so it could be that it is smaller than 'User Capacity' of
both
old and new drives.
