Error while activating the datasource during migration

Hi Guys,

When we were trying to migrate the datasources from 3.x to BI 7.0, we are encountering an error with the activation of the datasource. The datasource itself has been migrated but the ativation log gives and error

Error in activating the datasourc----RSO404

Has anyone encountered this issue? Your input is highly appreciated.
