BI4.1 migration (crystal reports error)

Hi,

We have migrated from 3.1 to 4.1 and all the crystal reports from 3.1 showing up as crystal report 2013 are failing with error Failed to load database information -Error code CRWEB00000119. Do the DB passwords not get copied over when migrated to Bi4.1 ? Do I need to update the connection password for all the reports?

Thanks
