As root use cp -a. That way as much as possible of the file structure gets
preserved. see the man pg for more info.
I have done the above by mounting the new disk on /home2 then doing cp -a from
/usr to /home2. After the copy is done mount the new disk as /usr.
test it for awhile to make sure everything is ok. Once you are satisfied
everything is ok put the machine in single usr mode umount the new
/usr and rm the old /usr to recover the disk space. remount the new /usr
go back to run level 3 and all should be well. It works well for me. I
have done this several times.
YMMV.

Unix IS user friendly. It's just selective about who its friends are.
