MSCRM 4.0-Data Migration tool

Hi friends,Today i do R&D on a new Microsoft-Utilty for data import in MSCRM 4.0 system. It's very fantastic tool compare to MSCRM 3.0 Data Migration tool.It's work for all entities (outerbox/customized) including customized fields.It does not come with CD but you need to download this utility from Microsoft Website.It can work from anywhere not needed server computer. It ask for a SQL server and by using MSCRM services it can push data into MSCRM.Even in siebel , there is no such fantastic utility.Great , I would like to say thanks to MS for this.
