Why PowerBuilder CloudPro
The only PowerBuilder to C# migration solution on the market that faithfully replicates DataWindow functionality, which is the key to making your migration project a "port" in terms of effort and risk.
Highly Automated
Automatically migrates 80-95% of PowerBuilder business logic to C#, including DataWindows, non-visual PowerScript, non-visual system functions, embedded SQL, NVOs and EAServer NVOs.
Port, Not Rewrite
Faithfully replicates your PowerBuilder business logic in C# so that a deep understanding of the original source code is not required for a successful migration.
Product, Not Service
Perform the C# migration by yourself using provided conversion tools and open-source C# libraries, eliminating the expense and risk of third parties to perform services.
Zero Dependency
Generates pure C# code and includes the source code of all the C# libraries. As such, there is zero dependency on any particular vendor or tool to maintain the migrated application.
How Does It Work
PowerBuilder CloudPro provides open-source C# DLLs (.NET DataStore) and migration engine (PowerScript Migrator) to enable developers to port PowerBuilder business logic to C#, which is the most valuable and complex layer in PowerBuilder applications. Watch the 5-Minute Video
.NET DataStore supports all DataWindow presentation styles and most non-visual DataWindow features in C#. As such, existing non-visual PowerScript can be readily mapped to C#, making your PowerBuilder migration to C# a "port" in terms of risk and effort.
Besides converting all DataWindows, the PowerScript Migrator converts most non-visual PowerScript, embedded SQL, and dynamic SQL. It also supports various PowerBuilder constructs, such as unbounded arrays, special blob handling, and system functions.
The resulting JSON data can be easily consumed by any UI framework that supports the REST and JSON standards, such as Angular, React, Xamarin, and Flutter.
5 Steps to Migrate PowerBuilder Logic to C#
It is not necessary to partition before conversion. PowerScript Migrator can automatically convert PowerBuilder objects (.SRD, .SRW, .SRU, .SRS, etc.) containing the relevant business logic to C#.

Design the blueprint of your C# services by defining the interfaces of your services. After that, you can automatically generate service implementations.

Load the necessary workspace in SnapDevelop and start converting both DataWindow objects and PowerScript business logic.
DataWindow Converter – instantly converts DataWindows objects to standard C# POCO models that can be maintained in any C# IDE.
PowerScript Migrator – automatically converts 80-95% PowerScript business logic to C# by mapping the functionalities from PowerScript to equivalents in .NET DataStore, SnapObjects and the .NET Core frameworks. It also supports various PowerBuilder constructs, such as unbounded arrays, special blob handling, and system functions.
Clean up problematic C# code, removing any unnecessary code (visual code, obsolete code, etc.) and resolving any compilation errors.
SnapDevelop – powered by Roslyn, highlights problematic C# code, suggests potential fixes for issues and automatically applies the selected fix.
PowerScript Migrator Error Reporting – generates inline comments in the converted C# code to efficiently alert developers areas that will require remediation.
Automatically scaffold the REST API (the controller) from the service and test.
REST API Scaffold Templates – rapidly construct the controllers for REST APIs with CRUD functionality.
REST API Tester – visual testing tool allows you to easily inspect, test, and debug REST APIs, without spending the time to create a UI or code JSON by hand.
C# Migration Result
The generated C# code and its open-source C# libraries adhere to .NET standards and open design principles so you can save significant time and money without having to compromise.
Any C# IDE
Maintain the migrated C# source code in any C# IDE, such as Visual Studio or SnapDevelop.
Any UI Technology
The migrated C# source code can be scaffolded into REST APIs, making it accessible by any UI technology.
Open-Source Libraries
All C# migration library code is available in the C# source code form (in addition to the compiled NuGet packages).
.NET Core Compatible
The .NET Core framework allows you to deploy to either Windows or Linux OS running a variety of Web servers or even go serverless (e.g. Amazon Lambda, Azure Functions, etc.).
API Architecture
PowerBuilder business logic is cleanly separated into C# controllers, services, and POCO models.
