FoxPro and Visual FoxPro were Microsoft database management systems that were discontinued in 2007, yet there are still many companies that are using systems and software designed around FoxPro. Migrating databases and systems when they reach end of life can seem difficult and expensive, but the alternative of continuing to use deprecated, legacy systems can prove far more costly.

A Brief History of Visual FoxPro



History of Microsoft Visual FoxPro



The relational database engine that powers Visual FoxPro, often known as VFP for short, closely integrates with the xBase capabilities of FoxPro to enable SQL querying and data management. Visual FoxPro is a full-featured, dynamic programming language, unlike other database management systems.

In addition to creating ordinary programs, it can also create middleware and internet applications. Standard software, middleware, and internet applications are created using Visual FoxPro database management systems.

Microsoft made a decision to stop working on Visual FoxPro so that they may concentrate their efforts on other products in their lineup. Visual FoxPro 9 was the most recent release, and the extended support period ended in 2015. Since Microsoft stopped supporting Visual FoxPro, there are no longer any updates or patches for security. The existing VFP apps now lack the ability to deploy bug fixes and vulnerability updates. Legacy applications such as VFP can therefore put companies data at risk. 

Is Visual FoxPro Really Dead?

FoxPro and Visual FoxPro were once considered incredibly fast and capable systems that many organizations came to depend on for database management. Like many other legacy systems, a major reason why it has continued to be in use today is because for those organizations it still works. With only a little scrutiny, however, that argument starts to falter.

Since Microsoft discontinued all Visual FoxPro support, there have been several years without any improvements or enhancements, no new security measures have been added, and it is getting more and more difficult to find qualified VFP programmers for support. The learning curve for new programmers isn’t worth their time. Visual FoxPro is marked as “End of Life” which means it is outdated software and with that come some serious issues, but the need for a speedy migration depends on your companies specific situation. Many aspects, both practical and economical, need to be considered and factored into the equation before making the leap.

Your VFP will not stop working instantly, but as time passes, mandatory Windows updates will eventually prevent your Visual FoxPro application from performing correctly. There is no guarantee that later versions of Windows will even run a FoxPro business application at all. At the very least, it is likely that some aspects will not function properly.



Is Visual FoxPro Really Dead



When determining the need to convert your Visual FoxPro to .Net, keep the following points in mind:

FoxPro application code support and maintenance are becoming costly and difficult to find. This is due to the lack of remaining FoxPro developers at hand and other progress made in programming efficiencies. Members in community support forums are now scarce, and classes are no longer being taught. The number of programmers in the pool with the necessary skills and knowledge is fast shrinking, and most have moved on to new languages or have retired.

FoxPro is a file based database system, which raises security concerns. There are constraints to how thoroughly data can be safeguarded from unauthorized access. Higher degrees of security cannot be introduced without affecting functionality.

Visual FoxPro is a 32-bit program. The world of computing is evolving towards a more advanced 64-bit architecture. VFP will no longer be able to run on a 64-bit only operating system which is problematic.

Visual FoxPro is not a product which is designed to work on a desktop web browser, and there is no mobile application development platform available for IOS (Apple) or Android operating systems. Since corporate services are moving online at a rapid pace, VPF is being left behind in the dust.

The way in which the new software is built is the most critical element in the cost of dataset conversion. The programmer must display txtCode in the new language by hand and assign it the same properties as the Visual FoxPro screen. This requires a lot of time and is prone to programmer error. At Intersoft, we have programs that automatically convert all of the labels, buttons, text boxes and more, thereby maximizing productivity and saving hundreds of hours on a major project. Many clients choose to convert to C#.NET with a SQL database, which is one of the most secure databases accessible, provides a great deal of flexibility, and is owned and backed by Microsoft.


Understanding the Need for Professional Migration

Visual FoxPro has been the programming language of choice for enterprise development since the 90’s. However, the evolution of cloud technology and the growing need for security, data privacy, performance and compatibility have rendered VFP business applications practically obsolete. As such, businesses that rely on VFP applications frequently find themselves reliant on an outdated technology to manage crucial business functions.



Foxpro To Net Migration



Maintenance Has Become Increasingly Difficult

Organizations lose sight of the fact that a competent developer has to maintain and command those legacy systems. In the case of older systems like FoxPro, it is getting harder and harder to find capable people that understand the outdated programming languages and technology, since few people are actually learning the system nowadays. This makes it expensive and often time consuming to keep an outdated system going. The fact of the matter is that Visual FoxPro support is becoming a business liability since it is no longer in the mainstream. There are many cases where organizations make concessions and devise workarounds rather than using the full capabilities of today’s modern technologies, which is far from ideal.

Innovation is impossible when using legacy software



Innovation when using legacy software



New technologies create new opportunities and new possibilities. With innovation come new ways of doing things, increased efficiencies, new integrations or better and faster ways of solving both routine and complex problems. If the systems that help drive your business are built on outdated technologies, none of that potential is available to you and you may lose a competitive edge. 

Case in Point: At InterSoft Associates we are working with someone who’s running important software on old laptop hardware that’s running Windows XP (which was released in 2001 and official support for it ended in 2014) and it is not even connected to the internet. But this laptop is running important mission-critical code.  It is still involved in managing important organizational operations, in addition to performing important business calculations. There is a great deal of a risk and a huge layer of inefficiency to have something critical running on old software on an old machine that cannot take advantage of on-line and real-time data and communications. InterSoft is currently migrating that software to an updated .NET environment. In addition to creating a more robust solution and adding new capabilities that could not have been previously considered, we have also given the client the ability to get data electronically, in real-time. This speeds up processes, eliminates transcription errors and helps the client realize the major difference and positive benefits this migration will provide.

Security is a Major Concern

As stated earlier, Microsoft has discontinued support for Visual FoxPro, so there are no longer any security, stability or content updates. Existing VFP applications are now vulnerable to security attacks since businesses no longer have the ability to easily hire programmers for this language. As maintenance becomes difficult, it’s harder to keep the security relationship intact between the “old” system and newer system, and maintain security compliant software. It quickly becomes apparent why a company would need an alternative platform, such as converting Visual FoxPro to Net. As new security threats emerge, updates are unavailable to patch outdated systems and the results can be catastrophic, expecially when dealing with customers personal or sensitive data.


Platform Options



Platform Options for Migration



Microsoft.NET Framework is a state-of-the-art Windows framework for creating web-enabled computer applications for Windows, Windows Server, Windows Phone, Azure and XML Web services. Because of its low total cost of ownership and licensing, ease of developing and modifying applications, and ease of deployment, .NET is suitable for businesses of all sizes. Visual FoxPro’s relational database software interfaces with and complements Microsoft SQL Server, making the migration of FoxPro databases to SQL Server relatively straightforward.


VFP to C#.NET Translation

Visual FoxPro and C# are incompatible with regard to automatic migrations/conversions.
The correct way to convert VFP to C# is to implement business requirements in a C#.NET application using either the same interface as the legacy application or a complete rewrite. The .NET professionals at InterSoft Associates are proficient in C#.NET app development and best coding practices if this is determined to be the best language for your specific needs. Our team collaborates with your team to ensure that everyone is completely in sync, so that we can perfectly automate and customize your applications at all levels.



Microsoft Net




VFP and ASP.NET Environments

InterSoft Associates specializes in managed migrations of Visual FoxPro to data-driven, high-performance ASP.NET web applications. We have an extensive track record of successfully migrating legacy VFP applications to ASP.NET. Due to its native optimization, built-in visual features, extensive toolbox and interface, and server-side execution, ASP.NET is suited for the development of large online applications. Using specialized tools that allow you to customize and control the transformation, InterSoft Associates extracts information from form fields, files, records and databases. Everything in the conversion project is mapped out, feedback is received and implementation is discussed prior to migration to ensure a smooth transition. We leave nothing to chance.


Why Are Companies Still Using FoxPro and Legacy Software?

Even with the many risks of using Visual FoxPro and obvious reasons to transition to a modern technology and upgrade, people continue to use old software because it works – or so they believe. It is serving some critical function that seemingly will not allow for the risk of interruption required to upgrade to the replacement software. This makes it easy to justify a delay or maintain the status quo, even for a software system that reached end of life over 15 years ago. Yet, migration must be done to keep systems and software high performing properly, and to help a business and its people do their jobs better, easier and  in a more efficient manner. 

Keys to Making a Successful Migration



Keys to a Successful Migration



Successfully Migrating from FoxPro to .Net is, of course, crucial to your business. When it comes to medium-sized data management applications, VFP was at the time unrivaled. However, as the size of the database increases, it has been demonstrated to slow down company operations, particularly on multi-user platforms. Modern business demands the use of newer platforms and technologies for efficiency and security reasons. The conversion process of an existing VFP program or entities to a.NET application cannot simply be done with a point-and-click wizard, full automation or third-party cookie-cutter solution due to the complexity. A successful migration requires competent programmers like those employeed at InterSoft Associates who are proficient in all aspects of migration, different approaches and specific nuances of various coding languages.

  1. Talk to an expert in the field who can understand why your legacy system is still in place and how a modern approach can significantly benefit from a FoxPro to .Net conversion. Consider hiring an expert team with a proven and robust development process, so that you are assured of a transparent custom development plan where everyone is on the same page, as well as a smooth installation execution.
  2. Understand the cost benefit and savings. A new or upgraded system should start by leveraging what is already there. In other words, you do not need to throw out what is working, even if you need certain elements updated or upgraded into new ways of accomplishing existing tasks. With the understanding of what is already available, combined with the problems that the old solution solves and what the creation of a new modern solution can improve upon, you can easily calculate the value and the benefits of migrating. Keeping an edge over competition is surely important to your business as well. Time and energy saved, output increased, opportunities uncovered – even your employees morale or communication improvements can all be a part of the solution, benefits and business case.
  3. Know the risks. When you are updating or rewriting software written on a legacy platform like FoxPro to new or improved technologies such as .NET, the old or existing platform will be eliminated for a more reliable, more secure and more capable platform which may need to be relearned. However, do not let these things be a surprise. Our expert analysis with a new perspective will help you understand these realities long before new code-crunching begins. This is why understanding the business problem is critical, rather than having a myopic view of just what the old system functionally did with an eye towards replicating that. The custom software development experts at InterSoft will provide solid answers on how we can take what you were doing and make it even better by employing the Visual FoxPro software. Migration is less about updating old code and more about upgrading the solutions to problems, which might require people to question and rethink the problem in the first place. Putting migration off because the old system “works” is usually a losing effort. At some point like an old worn out car for example, it stops running, will not be able to buy the components, or no places will have the mechanic skills or resources for proper repairs. The great news is that migrating from legacy systems does not have to be a painful path, unnecessarily expensive pricing, or even a significant interruption to existing workflows. We will ensure that the transition is a smooth one.



Visual FoxPro Migration



The following stages are taken throughout the customization and migration process:

  • Analysis and documentation of the current Visual Foxpro system
  • Recognizing instances of the Visual Foxpro system’s modules and the viability of conversion
  • Identify the most effective method for converting a program to a client-server (C#, SQL Server) or web-based application preference (ASP .NET, mySQL Server)
  • Estimate the amount and order of work that will be necessary for individual module customizations
  • Complete the design document, discuss the list of tasks on the roadmap, provide recommendations and estimate price
  • Implementation

At InterSoft Associates, our experts have the answers you need. We can evaluate what you are doing now, what needs to be done for upgrades or updates, and help conduct a migration that ultimately helps your business run better. If you’re still using mission-critical systems on outdated code or databases, let us show you possible alternatives, and how making coding changes and upgrades can be easier and way more cost-effective than you might think. We have helped many small businesses to large sized enterprises successfully convert FoxPro to .Net and we can help you too. We have five-star references and can provide names of previous clients, our programmers are interactive with every aspect of the project, and they have impressive qualifications and experience. We have extensive expertise in both FoxPro and .NET and knowing both languages perfectly is critical.

Converting a FoxPro application to .NET can be a complex and time-consuming process, so carefully consider your business needs and the pros and cons before starting the process.

Not all FoxPro features can be directly converted to the .NET framework which is a proprietary software framework developed by Microsoft that runs primarily on Microsoft Windows.

The best approach to converting a FoxPro application to .NET will vary depending on the specific application and its requirements.

Low cost of ownership, flexibility in rapidly developing and changing applications, SQL database development and ease of deployment, .NET is suitable for different sized corporations

Some common strategies for converting a FoxPro application to .NET include using a tool like Visual FoxPro to .NET Converter or rewriting the application from scratch.

The benefits of moving to .NET can be significant, including improved performance, scalability, security and in the long view, costs.


How does the FoxPro replacement software work?

VFP replacement software allows a company to replace their outdated, aging programming language /applications to more advanced technologies, and more stable and vendor-supported platforms that will allow them to meet the requirements and demands of a modern business.

How difficult is the conversion process?

VFP conversion/ migration projects vary greatly in size and complexity. After careful analysis of the company’s goals and customer needs, size limitations, security issues, or stability problems, the result may turn out to be simply a move of the VFP database to SQL Server or it may be a more complex process with a complete move of the application to a technology such as Microsoft’s .NET.

Some of the factors that can affect the difficulty of the conversion process include the type of conversion being performed, the amount of experience the person performing the conversion has, the availability of tools and resources, and the amount of money that can be allocated.

Before undergoing any replacement project, speak to a Software Consulting firm, line InterSoft Associates.

What are the key features to consider when choosing Visual FoxPro replacement software and the team to implement it?

Some key features that are important to consider include:

  • What are your business goals and current processes? Will the new software properly support them?
  • Scalability – Can it support your business growth?
  • Security – Will it help to eliminate any security vulnerabilities that your software may have.
  • More importantly, will it comply with all current and future security protocols via the use of strategic APIs?
  • Data storage – Will it allow for the storage necessary to provide actionable business analytics?
  • Mobile device integration – Visual FoxPro does not work well on a mobile device. This capability is a necessity in today’s remote workforce.
  • Flexibility and the ability to import and export data from a variety of sources, including other software programs, databases, and text files.
  • More control of your software and your business.
  • The ability to create infrastructure to keep the two systems (databases of the legacy applications & the new) in sync with one another until your team builds all the required functionality.
  • A team with significant experience with modernization projects that has also demonstrated expertise with VFP, such as InterSoft Associates.


What are the benefits of Visual FoxPro replacement software?

  • Upgrade from existing older VFP software technology that may be holding your business back while not being able to keep your data as secure as is necessary in today’connected world.
  • Addition of new software and tools that are better equipped to handle your business goals and evolution.
  • Easier to use and more intuitive – This includes the fact that there are far more software engineers that are familiar with .Net and SQL Server technologies. Additionally, the pool of
  • Visual FoxProengineers is rapidly declining.
  • More powerful with more features than the older VFP software.
  • More stable and reliable mobile device integration.
  • Better scalability and security.
  • More compatible with other software and systems.
  • .NET has a number of great solutions to rolling out new updates.
  • .NET has fewer compatibility issues since each application is independent from other parts of the system.

What are the drawbacks of Visual FoxPro replacement software?

Any VFP modernization project is going to be a significant undertaking. Although there are a few potential drawbacks to consider, there are way more benefits.

  • Cost: Depending on the replacement software, it could in the short run, be more expensive than keeping the outdated software. However, in the long run more money will be saved since the cost of upkeep and downtime with VFP issues could be significant. And using it on a mobile device is far from acceptable.
  • Hiring a firm to help that doesn’t have the experience for the replacement software project. Make sure that you engage a Software Consulting firm with a defined process, like InterSoft. We have a perfect record of success.
  • The learning curve associated with the new software. This should never be a problem with the right software partner. Software should be so intuitive that the learning curve is greatly diminished. Additionally, engaging all stakeholders will help to reduce this learning curve even further.


What is the process of converting Visual FoxPro to .NET?

The process of converting FoxPro to .NET is a multi-step process depending on the goals of the VFP modernization and the types of features the software provides. Multiple conversion options can be available from the simple such a conversion from DBFs to SQL servers to the complex involving coding a new architecture.


Before implementing a conversion, solicit the aid of a professional firm that is knowledgeable with converting VFP to a new replacement software. That company should:

  • Discuss the overall vision / goals for a project by determining the important aspects, potential time frame, priorities, wants versus needs, key challenges.
  • Analyze your existing VFP application. Understanding the current standing of services and products makes sure that the conversion effort produces maximum business sense.
  • Assess the size and complexity of the existing software and the company’s existing system.
  • Comprehend the separate conversion functions that will be required. When existing products and services are an interfaced multiplication program, it is essential to chart a migration strategy that minimizes quality issues and any possible downtimes in the future.
  • Analyze the potential risks and how to mitigate them.
  • Evaluate the best strategy for converting the old VFP application by deciding in what order and time frame which parts of the project to explore or engage in.
  • Document the plan of attack and then implement using the company’s own in-house resources and / or with outside assistance.

The testing process of the migration should be planned and properly mapped out so that VFP modernization is completed properly and effectively. This process will greatly mitigate any risks.
