Or to take it one step farther, as root:

cd /
tar -cf - opt | (cd /home; tar -xf -)
# check to make sure /home/opt looks like /opt, "du -s /opt /home/opt" 
might be useful
rm -r /opt
ln -s /home/opt opt

This is especially useful as Suse like to install 3rd party stuff into 
/opt, so it might grow some more.  Then as Greg points out, you can redo 
things next time you upgrade.  You might also think about LVN so you can 
grow stuff more easily.

HTH,
