tune2fs -U [old_partition_UUID] /dev/[new_partition]

will change the UUID of the new partition to the one of the original
one. If the partitions are inside the same machine, it is necessary to
change the UUID of the old partition, so that UUID's remain unique...
fstab needs adjusting if UUID are in use there too.
This is how I do it when moving systems around, it works, not to say
there isn't a better way !
