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


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


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

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.

Conversion Samples of PowerBuilder to React and Java

PowerBuilder programs consist of Workspaces (starting from PB 8.0 and higher, these are .pbw files). Conceptually, they are similar to Solution. These are text files consisting of paths to the Target files (.pbt files) that correspond to the concept of Project. The Target files are in text format, and each contains paths to the PowerBuilder libraries (.pbl files that store source code files in binary format). Typically a library with the same name as the Target file has a .sra entry point file.

To convert a PowerBuilder application, you need to extract all source files from the appropriate Workspace libraries (or Target, if PB version is less than 8). You can download Ispirer PowerBuilder Metrics to get a statistical report on PB sources, as well as extract source files from PowerBuilder libraries using Workspace, or a set of Target files, or a set of particular PB libraries (.pbl files) that need to be converted.

Once the source code is extracted, for each PowerBuilder library file, a corresponding folder named library will be created with all the source code extracted. The folders will contain source files with the following file extensions:

  • .SRD - DataWindow source files
  • .SRW - Window source files
  • .SRM - Menu source files
  • .SRU - Custom user object source files
  • .SRS - Structure source files
  • .SRP - Data pipeline source files
  • .SRF - Function source files
  • .SRQ - Query source files
  • .SRA - Application source files

Now you can use Ispirer nGLFly Wizard to convert it to your chosen target technology.
Basic source type conversion by extension:

  • .SRD - converted to 2 files. One file is named DatawindowObjectName.ts (located on the client) - the UI and code for the DataWindow object. The other file is called (located on the server) that contains the sql query.
  • .SRW - converted to 2 or 3 files. The files are named WindowObjectNamePage.tsx and store.ts (located on the client) - the UI and code of the Window object. If the source file contains sql queries, the file is converted to the server with sql queries.
  • .SRM - converted to 1 file named Menu ObjectName.tsx. – the UI and menu object code.
  • .SRU - converted to 1 file named store.ts for the non-visual object and 2 files named store.ts and UserObjectName.tsx - the UI and code of the User object.
  • .SRS - converted to 1 file named StructureObjectName.ts. The file contains a class with variable declarations from the PowerBuilder structure.
  • .SRP - not used for conversion.
  • .SRF - converted to 1 file named functionObjectName.ts. The file has a public function.
  • .SRQ - not used for conversion.
  • .SRA - converted to 1 file named applicationObjectName.ts. The contents of this file are used to copy into the project's entry point file in the same way as in the conversion sample.

After the conversion, you need to create a WPF application desktop project in Visual Studio and add the converted files from the results folder to it. There is the Ispirer framework for converting PowerBuilder to React and Java (IspirerFramework) in the results folder.
Note: this is a special framework provided by Ispirer. It extends the target technology to enable specific source code features.

  8. }

Try catch statement conversion:

PowerBuilderReact + Java
  2. try
  3. IDX = 1 / 0
  4. catch (Exception ex )
  5. IDX = 100
  7. IDX = IDX * 2
  8. end try
  2. try {
  3. idx = 1 / 0;
  4. } catch (ex) {
  5. idx = 100;
  6. } finally {
  7. idx = idx * 2;
  8. }
