Upgrading problems of Drag & Drop in RadGridView

I have developed a UI with features of Drag and drop from RadGridView to RadTreeView, it worked perfectly in old version (2011 Q3), after I upgraded to new version (2014 Q4), I got a warning message for the RadDragAndDropManager because of obsolete and the drag & drop cannot work now. My question is whether I must upgrade RadDragAndDropManager to DragDropManager suggested by some articles, or I still can use the RadDragAndDropManager without affecting the exsiting features. 
Please refer to attachment for details.

Hi Tian Xiang Cai,

Actually this is our feedback portal which should be used to track the process and log bugs and feature requests. Its purpose is not to assist our customers on their specific implementations. You can get assistance on your scenario using our Ticketing system or our Forums. This is why I would like to ask you to start a new thread in our forums or our ticketing system and keep the communication there.
However, before asking us to migrate your custom application, please try to migrate to the new DragDropManager using our documentation. The following article explains how such migration should be done:
http://docs.telerik.com/devtools/wpf/controls/dragdropmanager/migration.html

Also, I would like to turn your attention to the fact that we will assist you on your migration with suggestions regarding issues that you encounter during the process. The migration itself is up to you.

Please follow the instructions in the referenced article and contact us if you encounter issues that are not described in the documentation.

Regards,
Pavlov.

Hi Tian Xiang Cai,

You are right that the current implementation of the RadTreeView control does not work with the obsolete RadDragAndDropManager. It now uses the DragDropManager. If your application has custom drag&drop logic you will need to migrate it to utilize the new manager. 
With the current implementation of the RadTreeView control there is a way to force it to work with the obsolete manager, but our future plans are to completely remove the obsolete manager from our RadTreeView control as well as from our suite of controls. This is why the best way for you to approach this issue is to migrate to the new DragDropManager.

This is why we strongly encourage you to start migrating as soon as you have resource. If you encounter any issues during the migration we will gladly assist you with suggestions.
