And youre done
OK, what I did, and a couple of steps that I should have done
#cp -a /boot /root
#umount /boot
#gparted

#cp -a /root/boot /
#grub2-install /dev/sdb
At this point there are 2 more steps I should have done
#grub2-mkconfig -o /boot/grub2/grub.cfg
edit /etc/fstab to replace the UUID for mounting /boot
Somewhere in what I did or had to do in rescue mode messed up the
SELinux labeling, and one of the reboots relabeled. Overall it should
have been about a 10 minute procedure, but it took me about an hour. If
the partition that had to be shrunk was not boot, but something larger,
backing it up and restoring it might be more difficult and time consuming.
