Right, something like "copy -L" or "rsync -L" or, better, write a little 
script that uses readlink to get the target file name and basename to 
get the symlink name and then mv the existing file to the new location 
using the old/symlink name.  Something like the attached (very lightly 
tested) script...  Please feel free to make improvements and share results.
