Migrating reports to new database schema

Question

Hi,
My company has numerous Crystal Reports .RPT files that work against the existing database schema, but we are moving to a new database with a significantly different schema.
Rather than have to manually recreate new RPT files for all the reports, it would be nice if it would be possible to automate the process.
I have looked through the documentation for the various Java APIs and am completely confused as to whether this is possible and, if so, the best way to do it.
Any help would be appreciated.
Thanks,
Carl

I did have Crystal Reports version 9 installed, as well as version XI, but I uninstalled everything and only reinstalled Crystal Reports XI release 2, and I still have the same problem.
Here is the code I am running:
package reporting;
import com.crystaldecisions.sdk.occa.report.data.*;
import com.crystaldecisions.sdk.occa.report.lib.*;
import com.crystaldecisions.sdk.occa.report.application.*;
import java.io.*;
import java.util.*;
public class TestReporting3 {
  public TestReporting3() {
  public static void main (String [] p_Args) {
    try {
      String path = "C:\\Samples\\Test3.rpt";
      ReportAppSession ra = new ReportAppSession();
      ra.createService("com.crystaldecisions.sdk.occa.report.application.ReportClientDocument");
      ra.setReportAppServer("inproc:jrc");
      ra.initialize();
      ReportClientDocument clientDoc = new ReportClientDocument();
      clientDoc.setReportAppServer(ra.getReportAppServer() );
     clientDoc.open(path, 0);
      ConnectionInfo info = new ConnectionInfo();
      info.setKind(ConnectionInfoKind.SQL);
      info.setPassword("client");
      info.setUserName("client");
      PropertyBag bag = new PropertyBag();
      bag.put("Server Type", "JDBC (JNDI)");
      bag.put("Database DLL", "crdb_jdbc.dll");
      bag.put("Connection String", "Use JDBC=b(true);Connection URL=s(jdbc:derby://localhost:6652/agency;create=true);Database Class Name=s(org.apache.derby.jdbc.ClientDriver);Server=;User ID=s(client);Password=;JDBC Connection String=s(!org.apache.derby.jdbc.ClientDriver!jdbc:derby://localhost:6652/agency;create=true!user={userid}!password={password})");
      bag.put("Use JDBC", "true");
      bag.put("Database Class Name", "org.apache.derby.jdbc.ClientDriver");
      bag.put("Server Name", "jdbc:derby://localhost:6652/agency;create=true");
      bag.put("URI", "!org.apache.derby.jdbc.ClientDriver!jdbc:derby://localhost:6652/agency;create=true!user={userid}!password={password}");
      info.setAttributes(bag);
      clientDoc.getDatabaseController().replaceConnection((IConnectionInfo)clientDoc.getDatabaseController().getConnectionInfos(null).get(0), info, null, 0);
      clientDoc.saveAs("NewTest3.rpt", "C:/Samples", 0);
      System.out.println("Done");
    } catch (Exception ex) {
      ex.printStackTrace();
The exception is being thrown by the line clientDoc.getDatabaseController().replaceConnection(...);
