Problems with Updating Datasource...

I have a report that accesses an Oracle datasource via an ODBC connection. I migrated the data to a new MSSQL 2008 server from the Oracle database. It appears however, even though it is connecting to the new datasource and the data is coming from the correct source, it is STILL authenticating with the old connection. I haven't found a way around this short of removing the datasource which forces you to essentially rebuild all the fields from scratch.

I am using Crystal Reports 2011 and Crystal Reports for Visual Studio 2010.

Any suggestions or is this a known issue that has yet to be resolved?
