PowerBuilder Migration to C#

@augurstech

A Warm Hello! We are readily available to start working on this project! I have read your job posting and definitely help you in Migrating from PowerBuilder/MySQL to a modern stack like C#/.NET is a critical step toward improving scalability, maintainability, and long-term performance We understand that this is not just a code rewrite, but a full transformation involving database redesign, migration tooling, and system optimization while ensuring business continuity. Key Point: - Migrate legacy PowerBuilder modules to a modern language (preferably C#/.NET) - Optimize and potentially redesign your MySQL database - Leverage automated migration tools where possible - Ensure the system is clean, maintainable, and future-ready We’d be happy to review a sample module and provide a more precise migration plan and effort estimate. Looking forward to helping you modernize your platform. Best regards, Ana

Hello, I understand you want to migrate several in-house modules from PowerBuilder/MySQL to a modern stack like C#. This will involve translating business logic, reorganizing data access, and optimizing the database schema for better performance and maintainability. My approach is to first map the current data and workflows, then implement a clean C# architecture with a SQL Server or MySQL backend as needed. I’ll apply a phased migration: (1) create a robust data model and API layer, (2) gradually port modules with parallel test suites, (3) optimize queries, indexes, and stored procedures, and (4) establish automated migration tooling to keep future changes smooth. I’ll also address cross-language integration, error handling, and deployment considerations to minimize downtime and ensure data integrity. What specific modules are highest priority for migration and what is your target go-live window? What is your preferred backend stack (SQL flavor, hosting), and do you require a gradual cutover or a big-bang release? Are there existing test suites or data quality rules we must preserve during migration? Are there compliance or security constraints we should align with? Thanks for the opportunity. I’m ready to discuss your preferred tech stack, migration window, and success metrics so I can tailor a precise plan.

Hi, I can help modernize your PowerBuilder/MySQL modules by migrating them to a modern C# (.NET) architecture, including database redesign, schema optimization, and safe data migration strategies using automated tools where appropriate. I’ll refactor business logic into maintainable services, implement a clean layered architecture (API, service, data access), and ensure performance and scalability improvements during the transition. The process will include careful mapping of legacy functionality, staged migration, testing, and validation to avoid data loss and downtime. I have experience in legacy system modernization and can deliver a structured, low-risk migration path with clear milestones.

@adisonw

Hello! I'm excited to see your project — it aligns with my experience. I have experience modernizing legacy systems and migrating applications from older stacks into maintainable, scalable architectures. I’ve worked on projects involving database refactoring, API redesign, and transitioning business logic into modern languages such as C# with .NET. For your migration I would start by analyzing the existing PowerBuilder modules and MySQL schema to understand dependencies, data flow, and performance bottlenecks. I typically redesign the database where needed to improve structure, indexing, and scalability, while ensuring data integrity during migration. On the application side I would rebuild the modules in C# using .NET, structuring the system with clean architecture principles and reusable services. Where possible, I can leverage migration tools to accelerate data transfer, while validating results through testing and staged rollouts. My approach focuses on minimizing downtime, maintaining backward compatibility during transition, and delivering a system that is easier to maintain and extend long term. Questions: How many modules need to be migrated and are they tightly coupled within the current system? Do you prefer a phased migration with parallel systems or a full cutover once development is complete? Hope we can team up and make this project a success! Thank you for considering my proposal.
