converting Clipper to Harbour - any companies out there?

[A Platt]

I have been working with a clipper-based programm and thinking on a conversion towards Harbour.

Not being a programmer myself, just user and sometimes I adapt some settings etc in the source code I and my company would like to seek professional help on the reprogramming/resetting towards Harbour.

I wonder if anyone out there who has dealt with pros doing this?

The complete clipper prg-files etc. are available, minor re-programming is currently done by myself including compilations, but I would like to outsource the re-programming and then have the Harbour program files for myself in order to re-program in the future.

Many thanks

Andy

Hi Andy,

I have experience migrating software from Clipper to Harbour. In my experience, it is generally a straightforward process.

I would be happy to discuss how I can assist you with your project.

Ciao,

Matteo

Hello Andy,

I use Harbour together with the Harbour MiniGUI Extended framework (https://www.hmgextended.com/) for developing business management systems. My experience ranges from programming in Clipper to migrating legacy systems to modern environments based on Harbour.

I am an active contributor to the Harbour MiniGUI Extended project, and I have contributed code and practical examples. I am attaching some screenshots of a sample system I developed, which is included in the official distribution as a usage reference.

Inventory Billing System - application

I am available to contribute to your project.

Best regards,

Hello,

I can convert your program even to SQL or to Advantage Database Server. I have already done such migrations before.

I can also provide backward compatibility. In that case, you will have a single source code base that works both under Clipper and Harbour. You can also keep using the old RDD if you prefer.

Best Regards

Hi Andy,

Thank you for your message.

The migration of legacy CA-Clipper systems to Harbour is precisely my area of specialization. I have been working with Clipper-based applications since 1989 and currently focus on modernizing legacy DOS systems into 32/64-bit Harbour environments while preserving their original logic and visual identity.

Recently, I completed the full migration of a large CA-Clipper 5.2e system to the latest Harbour version. The project was executed with the following principles:

• Maximum preservation of original PRG source code

• Minimal structural changes to maintain compatibility and readability

• Modernized printing system (conversion from legacy EPSON ESC/P emulation to native PDF generation)

• Preservation of the original user interface, with optional improvements implemented only upon client approval

• Clean and maintainable Harbour build structure

Since you mentioned that you would like to keep the Harbour source files for future maintenance, I fully support that approach. In my last migration project, I:

• Delivered all Harbour project files

• Documented the changes introduced during migration

• Provided step-by-step guidance on installing Harbour and required tools

• Explained the build process so the original developer could independently compile and maintain the system

My goal is not only to migrate your system, but to ensure you and your company retain full autonomy moving forward.

In addition to migration, I can also introduce optional improvements such as:

• PDF reporting

• Performance optimizations

• Improved database handling

• Modern compiler structure

• Optional GUI or enhanced console interface (if desired)

I provide full post-migration support and am available for future enhancements and maintenance.

If you would like, we can schedule a brief call to discuss the size of the system, external libraries involved, printing routines, and database structure. Based on that, I can provide a structured scope and timeline.

I would be pleased to assist you with this transition.
