Migrating Time Machine Volumes on macOS

macmacostime-machine

I have two external drives I use for Time Machine backups. On each drive, I have Time Machine backups for multiple computers. My primary computer has a large disk, and the associated external Time Machine drive recently warned that it was getting low on space. I would like to migrate the profiles from all other computers off of this drive and on to the other external drive. How can I do this?

The key difference between my problem and other questions is that I don't want to just move the whole Time Machine volume to another drive. I want to just move some profiles. Ideally, they would migrate to the pre-existing other volume. I'm ok if I have to create a separate partition, but that would be second best.

You can move a whole drive using Disk Utility using block copy and it comes free with your Mac. You could then delete the profiles you don't want from your drives. This method doesn't move a single profile, though. You can't just do a straight copy because the 'hard links' are copied over as whole files rather than just links.
