eCheck if it's safe to move a directory and replace it with a symlink

Say the directory you want to move has absolute path DIR. A case where it is NOT safe: that directory has either - absolute path symlinks to within DIR itself. For instance DIR/link -> /PATH/TO/DIR/file. EDIT: as pointed out in a comment below, this should still be safe. - relative path symlinks to outside DIR. For instance DIR/link -> ../../other_dir/file. Is there a tool that checks whether it's safe to move a directory and replace it with a symlink?
