No Use of Data import /Export framework

Hi All ,

Seems to be AX data migration tool - Data import /Export framework is half -baked tool . It is not at all working to import the data in AX 2012 R2 .it is throwing errors to import the data .

Just i would like to know your opinion that did you succeed to import the data in AX 2012 using Data import /Export framework ?

I am really surprised that How MS had released this tool without proper testing ?

Share your experiences .

Thanks in advance.
