We do enterprise reporting from MOSS integrated SSRS.
We yesterday migrated from MOSS 2007 - SSRS 2005 to MOSS 2013-SSRS 2012 (as service application). But after migration we lost the Data Source link for all the 700 reports. It is ridiculous to go to each of the 700 reports and reestablish the Data Source link .
Please help. Does anyone have any work around (even upsupported)?
