Difficulty switching DB servers without manually tweeking report

Question

I have an ASP project with a number of crystal reports. The database is SQL Server and IDE is VS 2010. The ASP pages do not have a problem talking to the database, but I cannot switch the report from one database server to another without manually adjusting the report to the current server (I do this by going into the report > Field Explorer > Database Fields > Set Database Location). Without this, I get a "database logon failed" page in spite of code that gives the correct logon info to the report. Manually switching the reports back and forth has the potential to create a lot of tedious busy work so it would be nice to do it all through code. I'm aware of the Push method and that it would probably avoid this issue, but set that aside for the sake of argument. Having stepped through the code, all the settings from the config file are correct and everything works correctly after the report change.
My question: is there a way to switch databases fully through code?
Here is the current logon code:
ReportDocument cryRpt = new ReportDocument();
TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
ConnectionInfo crConnectionInfo = new ConnectionInfo();
Tables CrTables;
cryRpt.Load(AppDomain.CurrentDomain.BaseDirectory + ReportName);
crConnectionInfo.ServerName = ConfigurationManager.AppSettings\["ReportServerName"].ToString().Trim();
crConnectionInfo.DatabaseName = ConfigurationManager.AppSettings\["DatebaseName"].ToString().Trim();
crConnectionInfo.UserID = ConfigurationManager.AppSettings\["ReportUser"].ToString().Trim();
crConnectionInfo.Password = ConfigurationManager.AppSettings\["ReportPassword"].ToString().Trim();
crConnectionInfo.IntegratedSecurity = false;
crConnectionInfo.Type = ConnectionInfoType.SQL;
CrTables = cryRpt.Database.Tables;
foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables)
    crtableLogoninfo = CrTable.LogOnInfo;
    crtableLogoninfo.ConnectionInfo = crConnectionInfo;
    CrTable.ApplyLogOnInfo(crtableLogoninfo);
CRViewer.ReportSource = cryRpt;
CRViewer.RefreshReport();
I have also tried this with the same result:
cryRpt.SetDatabaseLogon(ConfigurationManager.AppSettings\["ReportUser"].ToString().Trim(), ConfigurationManager.AppSettings\["ReportPassword"].ToString().Trim(), ConfigurationManager.AppSettings\["ReportServerName"].ToString().Trim(), ConfigurationManager.AppSettings\["DatebaseName"].ToString().Trim());
