i want to migrate crystal reports from Business Objects(XIR2)  crystal release 2 to Business Objects (4.0) Crystal 2011 version . Do you have challenges when you was doing these Platform migration .Please let me know .It would be more helpful to me

Note: 1) few reports are pointing to XML data source
