Under an elevated shell? I *did* move Cygwin installations using robocopy and the above works for me.

That doesn't make sense either. The symlinks created by setup or Cygwin tools are using POSIX paths, not Windows paths. Since you're moving the Cygwin installation as a whole, the reference point for the POSIX root dir moves as well. From the Windows (i.e. robocopy) perspective, those symlinks are simple files with arbitrary content and the DOS system bit set.
