Yes, and you also need to delete the content in the original directory
tree, or else you don't recover the space. Most of this is most easily
done from a live/rescue OS with the host OS offline, though it can be
done online with a bit more work.

If you're moving /usr it is wise to rebuild grub from chroot, making a
new initramfs. Systemd requires /usr during boot and gets quite upset
if it can't find it. I'm aware there is controversy about putting
essential system software in a tree named '/usr' and I'm not going to
add to it.

There are many web articles on how to add and mount a new drive, but
hardly any (mostly one for Ubuntu repeated widely) for actually moving
an existing directory tree, especially a system one like /usr. I
hesitate to offer details as it is a long time, pre-systemd, since I
last did it.
