How to change the connection for a recurring report

I have a group of reports running in production on recurring schedules. I need to update the database connection for these as we are changing our server environment.

I open the report in Crystal Reports 11 and changed the database connection saved the report back to the Enterprise Server location (I also have a backup of the original). When I preview the report using the Central Management Console, the report uses the updated database connection info. When I test the recurring report I get a logon failure. When I go to the instance to look at the database logon for the recurring instance it shows the old database connection.

How can this database connection get updated for the current group of instances for these recurring reports?

Thanks
