ECMAScript moveTo move document to another web in same site

Question

I have studied and used the following post to attempt to move a document: moveTo and moving documents from one library to another

This works perfectly when moving documents to different libraries in the same web or even folders in the same library but I am trying to move a document to a different library in the parentweb.

1. Is this possible?
2. How can I do it?

So far I have changed the code to this which is returning error 0x002 "Illegal Argument Exception":

            //current web is "/web/sub/";
            var context = SP.ClientContext.get_current();
            var site = context.get_site();
            var dst = "/web/lib/fold/";
            var dstweburl = dst;
            dst += "myfile.txt";
            var destweb = site.openWeb(dstweburl.substring(0,dstweburl.substring(0, dstweburl.length-1).lastIndexOf("/")+1));
            var destfold = destweb.getFolderByServerRelativeUrl(dstweburl);
            context.load(destfold);

            var web = context.get_web();
            context.load(web);

            var currentLib = web.get_lists().getById(unescape(ListGUID));
            var currentItem = currentLib.getItemById(ItemID);
            context.load(currentItem);
            var File = currentItem.get_file();
            context.load(File);
            //Excecuting executeQueryAsync to get the loaded values
            context.executeQueryAsync(
                function(sender, args){
                    if(File!= null){
                        if(moveFlag){
                            File.moveTo(dst, SP.MoveOperations.overwrite);
                        }
                        else{
                            File.copyTo(dst,true);
                        }
                        //Excecuting executeQueryAsync to copy the file
                        context.executeQueryAsync(
                            function (sender, args) {
                                $("<div>Item moved/copied successfully.</div>").appendTo("#response");
                            },
                            function (sender, args) {
                                $("<div>Error moving/copying item. 0x002</div>").appendTo("#response");
                            }
                         );
                    }
                    else{
                        $("<div>Error moving/copying item. 0x001</div>").appendTo("#response");
                    }

                },
                function(sender, args){
                    $("<div>Error moving/copying item. 0x000</div>").appendTo("#response");
                }
            );

I have instead used the SPServices JS library. Code for moving with the metadata is here: Copy document from one site to another
