UUID shown by blkid is for file system, while PARTUUID is for "partition" of GPT.
Therefore you can not use a file system label program to change that, instead you have to use a GPT disk program to do that, like "sgdisk".
E.g.
sgdisk --partition-guid=1:R /dev/sdg
will modify /dev/sdg1 with a new random GUID.
Run "man sgdisk" for more details.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
3TB data disc with one NTFS partition cloned to new 4TB disc.
Using both drives at the same time is not possible.
"two drives with same id detected" or similar.
blkid shows the two partitions have different UUIDs but the PARTUUID ist the same.
The name in Windows for the new disc is the same as the old "ST3000DM0001"
ntfslabel --new-serial did not change the PARTUUID
Any idea how to change the PARTUUID?
