Migrate PB Apps to Open Technologies

Architecture and UI Modernization

An effective migration approach to bring PB Skills and Applications to the next level

Leverage the Appeon Roadmap

  • PB 2019 contains tools for converting datawindows to C# data models, and a new Web API target to create a template project
  • PB business logic (datawindows, data manipulation logic, embedded SQL), the core part of every PB application, can be migrated to a Web API with .Net Core, multi-platform and server-side

Effective Approach

  • You migrate the PB business logic (with our help)
  • We rewrite the UI that will call this newly migrated PB business logic
  • You control the progress of the migration:
    • Agile Project Management and Development services
    • UI specifications approved by you

Specifically created for PowerBuilder

  • Consulting, training, mentoring services specifically designed for PowerBuilder customers, to help them migrate to a new and modern architecture

Finally, the UI end-users are waiting for

  • Our technology stack allows us to create the UI of your dreams:
    Browser, Mobile, Mac, Multi-platform desktop cloud
  • Not only a full migration: you can redesign a specific subset (e.g.: Mobile module, a Browser-based module and so on)

The Migrate to PB Open Program

3 phases: Assess, Evaluate, Migrate


  • On-site consultancy to assess the application, the environment, the structure, the framework, the skills
  • Definition of a pilot implementation (smallest interesting subset to be migrated)
  • UI requirement specification for a pilot implementation
  • Migrate the first subset of PB business logic as Web API, based on the pilot implementation


  • Evaluate the effort to:
    • Build the pilot implementation
    • Train the PB development team to Web API migration
    • Mentor and support the PB development team
  • Upon approval: we rewrite the UI, according the specifications and linked to the Web API


  • Select a subset of the application (e.g.: a module, or a specific target, like the Mobile app, or a browser-based app)
  • Specify the new UI requirements and evaluate the UI rewriting effort (requires your approval)
  • Migrate and convert the PB business logic (with our support) while we rewrite the UI

Different from a standard migration approach

  • “Legacy code” migration is not new
  • PB2019 is not legacy any longer, but our code and our applications are. Specially architecture and UI!
  • It’s very risky to rewrite the business logic from scratch:
    • Will it work?
    • Who will maintain it?
    • Who will be the new Application Domain expert?
    • Can we convert PB developers to a new technology?
  • With our program:
    • PB developers will embrace .Net technology, will migrate the PB business logic to a Web API, will maintain it
    • UI will finally meet end-users’ needs
    • No business logic rewriting
    • No business logic duplication
    • Any technology for the front-end
