NGLFly Wizard for Automated App Conversion

NGLFly Wizard Logo

NGLFly Wizard is a tool for automated application conversion. This solution makes it possible to translate code from one programming language to another automatically, while preserving the initial functionality of an application. Based on an intelligent proprietary algorithm, the tool analyzes the syntax, semantics, mapping data types, control structures, function calls, and even code structures that do not have equivalents in a target technology. Based on the analysis, nGLFly Wizard applies all the relevant conversion rules from its knowledge base core and translates the source code to the target technology.

NGLFly supports both legacy and most popular programming languages, such as COBOL, Delphi, Informix 4GL, Powerbuilder, C#, Java, Python, JavaScript, and others. To ensure a smooth translation process, our support experts are available to assist with tool configuration or resolve any issues in a timely manner.

Turnkey Migration Service

The entire conversion process can be divided into several stages:

  • Preparation. During the preparation stage, the focus lies on planning and preparing applications and infrastructure for migration to a new environment or platform. This involves assessing their current state to gauge compatibility with the target environment and defining the migration strategy, timeline, and required resources. Additionally, identifying potential risks and challenges associated with the migration process and devising mitigation strategies are integral parts of this stage.
  • Assessment. During the assessment phase, the team conducts a thorough analysis of the source code to accurately estimate the migration timeframe and cost. As a first step, we apply Metrics - a set of Ispirer’s proprietary assessment tools tailored to different programming languages. These metrics automatically analyze the source application, gathering essential information and generating a comprehensive report. This report combined with the insights gathered during the expert review of the source code serves as the basis for estimating the delivery time and cost of the migration project.

APP Services general

  • Automated conversion with Ispirer Toolkit. Considering the inherent characteristics of the original technology, Ispirer Toolkit can provide varying default levels of automated code conversion. Importantly, Ispirer experts can iteratively customize the tools to meet the specific properties and patterns of the source code and thus increase the level of automated conversion.
  • Post-conversion refinement. Often an application may contain code segments that are impossible or ineffective to migrate automatically. In such a case, our team of Ispirer experts leverages their extensive knowledge and expertise to meticulously execute the manual migration of the remaining code. Moreover, this stage involves fine-tuning the application to improve its performance in the new environment. This may include optimizing resource allocation, tuning database configurations, and addressing any performance bottlenecks.
  • Functional testing. Functional testing ensures that the migrated application behaves as expected and meets the functional requirements in the new environment. The Ispirer experts run hundreds of tests to ensure that the converted application is reliable and meets user requirements, business objectives, and industry standards.

Why choose conversion over developing a new app?

Seasoned Team

Same functionality, new application

Migration does not require labor-intensive development of new functionality from scratch. Your application will be converted to a new technology while maintaining the original functionality

Enhanced efficiency

Architecture preserved or modified

By default, automated conversion implies preserving the initial architecture which is easier to maintain. It is also possible to transform the app architecture, for example, from desktop to the web and thus improve accessibility and scalability

Integrate

Legacy System Transformation

Migrating legacy systems to modern architectures or platforms can future-proof your application, making it easier to maintain, update, and extend in the long term

Advanced security

The speed of conversion

Migrating an application is much faster than creating a new one from scratch. Automated migration with Ispirer Toolkit minimizes manual effort and may speed up the delivery by 2-3 times

Growth

Performance and Scalability

Through conversion, you can optimize the application's architecture and infrastructure, improving scalability and performance without the need to rebuild everything

Advanced security

No need for documentation

To perform the conversion, we go by your source code. There is no need to have detailed documentation in place to start the conversion as is the case with development

Conversion Samples of Delphi to C# WinForms

Ispirer Toolkit analyzes all object dependencies during the conversion process and provides not only line-by-line conversion, but resolves type conversions as well. In addition, the software understands and transforms the necessary inheritance dependencies. It parses the entire source code, builds an internal tree with all the information about the objects, and uses it in the migration process. For more information review the code samples below.

What Our Customers Say

"The tool is easy to use and maintain and it has also improved a lot in terms of performance. This last point was a huge pain and the solution you gave was key for the project succeed. I would not hesitate to suggest Ispirer migration services to other companies."

"Ispirer has been a great choice for the migration of our dated software, thanks to its very flexible and supportive team. All our requests were handled in an accurate manner, and every single request was performed promptly."

"This approach was very successful avoiding any confusion at the first stage, and achieved high conversion rate in the end. The project was completed successfully, they say they couldn't make it without MnMTK 2017 and excellent extension support from lspirer."

"We had an old Borland Delphi 7.0 project, which was brought back to life. Ispirer had offered us a timely and financially attractive conversion of the application. The work was performed promptly."

"We were impressed with the knowledge, professionality, hard work and enthusiasm of the Ispirer team. Through this Migration Project we have a solid base for further expanding our application."

"I really had a surprise after migrating. The quality of generated code after conversion is very high. The tool is very intuitive and easy to use. I believe that there is no such a good tool as SQLWays to do code migration and I really recommend it."
