Move group into another group

Does this help?

// move groups of a certain name into group of a certain name;
// 2015, use it at your own risk;
#target "photoshop-70.032"
if (app.documents.length > 0) {
var myDocument = app.activeDocument;
var name1 = "Shine";
var targetName = "Shine All";
var targetGroup = layersWithName (targetName);
// if exactly one group qualifies;
if (targetGroup.length == 1) {
// collect groups;
var theGroups = layersWithName(name1);
// process groups;
for (var m = theGroups.length - 1; m >= 0; m--) {
  moveTo(theGroups[1], targetGroup[0][1]);
  };
}
else {alert ("too many or too few groups called »"+targetName+"«")}
};
