Excel Output when Converting 6i Reports to 10g

Question

I am attempting to convert about 25 reports from Oracle Reports 6i to Oracle Reports 10g (10.1.0.4.2). The existing 6i system uses the Oracle Portal for job submission. The report server and our Oracle database are on Sun/Sparc/UNIX computers for both 6i and 10g. We have no space issues. In 10g, users will submit reports from Oracle Forms, running on Windows desktops.
I am an experienced programmer in Windows reports and forms using MS-Access and Visual Basic. I am new to Oracle Reports and Forms.
The existing 6i reports were set up so that a single report can be generated in either PDF or Excel format by just changing the DESFORMAT parameter from PDF to DELIMITED. We also have multiple optional parameters. In 10g, I cannot get the Excel to generate when there are groupings or summaries in the PDF version.
In the 6i version, headers, footers, and summary lines were enabled or disabled in appropriate triggers through PL/SQL code:(IF :DESFORMAT = ‘DELIMITED’ THEN RETURN TRUE/FALSE;). In order to get the Excel spreadsheet we use the following URL: http://server1/reports/rwservlet?my_reports&report=labor_detail&destype=cache&desformat=delimited&mimetype=application/vnd.ms-excel&paramform=no&BEGIN_DATE=01%2F01%2F2009&END_DATE=01%2F31%2F2009&RESOURCE_TYPE=100
When I converted the 6i report to 10g, I changed the following properties to support web layout:
•     Report > Report Escapes
•     Report > XML Settings
•     Web Source: <%@ page contentType. . . and <rw:include. . .
•     Paper Layout> Body> Web Settings > Table Attributes
•     Changed triggers from :DESFORMAT = ‘DELIMITED’ to :DESFORMAT = ‘SPREADSHEET’; also tried deleting these triggers altogether
In hopes of getting something to work, I rewrote a report for Excel only, but it will only accept one parameter. When multiple parameters are provided, it displays the correct data, but in paper layout.
In the 10g version that is for Excel only, we use the following URL:
http://server2/reports/rwservlet?my_reports&report=labor_detail&DESTYPE=CACHE&DESFORMAT=SPREADSHEET&WHERE_CLAUSE%20AND%20WORK_DATE>=’01/01/2009’%20AND%20WORK_DATE<=’01/31/2009’%20AND%20RESOURCE_TYPE=’100’
I tried submitting the 10g report with the &MIMETYPE parameter, and it appears to open up the PDF file in Excel. I am using .rdf format, but I don’t see any difference when I use .jsp format.
Is there a way I easily convert my existing reports and parameters so that they will produce Excel format?

Thanks to everyone for their suggestions. I don't think I need to use the Forms Migration tool since the form has already been migrated from 6i to 10G. (Since I am now using an existing 10G form rather than trying to convert my 6i form.) I will check the FORMS_PATH. Is that in my registry file? I'm pretty sure the library has been compiled in 10G since it is attached to the other 10G forms I have and they work fine. But, just in case, how do I compile the library? And back to the FORMS_PATH: I still have the 6i version of Forms Builder on my PC. Will changing the path affect using 6i? Probably yes.
