How to transfer file shares from one server to other

Dear All,

In our office we have one DC cum file server and OS is Windows 2003 and we have new with OS server 2008 r2 Domain controller. So we need to transfer the files and folders with sharing and security permission to the new server.

I tried using File Server Migration tool but it is creating share name such as oldsevername_sharename which I do not want.

I tried with robocopy, it is copying only security permission not the sharenames.

Anybody has idea which is the best way to transfer the shared folders to other server without recreating the shares.

Thanks in advance

Regards,

Sundar
