I have an in-house ERP currently running on ASP.NET 4.5 (C#), classic HTML and Telerik controls. The back-end logic—database, stored procedures, triggers, views and data tables—works well in SQL Server, so those pieces will stay exactly as they are. What I need is a complete front- and middle-tier migration to ASP.NET Core 10 paired with Angular 22, styled with Tailwind CSS. The goal is three-fold: noticeably better performance, a modern UI/UX that feels crisp on any device, and an architecture that scales cleanly as our user base grows. You’ll receive full access to the existing codebase and the database so you can mirror current functionality while shedding the legacy Telerik layer. Key expectations • Re-implement all present features untouched in behavior, using ASP.NET Core controllers, services and middleware where appropriate, and Angular 22 components on the client side. • Keep the SQL schema and every stored procedure intact; only the presentation and API layers should change. • Apply Tailwind CSS for layout and styling so the interface looks fresh but remains lightweight. • Deliver a clean, well-commented codebase, migration scripts (if any), and concise deployment notes that let my team spin the new solution up in our existing IIS or container environment. • Before hand-off, run end-to-end tests to confirm parity with the old system and demonstrate improved load times. If you’ve already moved complex enterprise apps from Web Forms or MVC 5 to .NET Core and modern Angular, this project should feel familiar. Let’s talk timeline, staging strategy and any questions you have about the current ERP modules, then get started. Comment or reply with [login to view URL] to prevent the spammer

Transforming a legacy ERP system built on ASP.NET 4.5 with Telerik controls into a modern, scalable platform is a critical step toward enhancing performance and user experience. The challenge lies in preserving the robustness of the existing SQL Server backend while completely overhauling the front- and middle-tier layers using ASP.NET Core 10 and Angular 22. Achieving a seamless migration that respects current business logic, maintains feature parity, and delivers a responsive, device-agnostic UI requires a deep understanding of both the legacy architecture and cutting-edge web technologies. The migration will leverage ASP.NET Core’s middleware, controllers, and services to create a modular and maintainable backend API, while Angular 22 will provide a dynamic, component-driven frontend that integrates Tailwind CSS for a lightweight, modern design. The approach ensures that the existing SQL schema, stored procedures, and triggers remain untouched, preserving data integrity and business rules. Comprehensive end-to-end testing will validate functional equivalence and demonstrate measurable improvements in load times and scalability. Detailed, well-commented code, along with clear migration and deployment documentation, will empower your team to manage and extend the new system effectively. Commitment to delivering a robust, scalable solution that aligns with your performance and UX goals is paramount. A collaborative dialogue about timeline, staging, and module-specific nuances will ensure a smooth transition without disruption.

Hi there, The most critical part of this migration is preserving your existing business logic exactly as is while modernizing the UI and architecture without breaking anything, and that’s something we’ve handled in multiple legacy-to-Core transitions. We’ve worked on ERP migrations from ASP.NET Web Forms/ MVC to ASP.NET Core & Angular, keeping SQL Server (SPs, triggers, views) untouched while rebuilding the front-end and API layers for performance and scalability. How we’d approach your project: - Phase 1: System Understanding & Mapping - Phase 2: Migration & Rebuild - Phase 3: Validation & Optimization Key strengths we bring: - Strong experience with enterprise ERP systems & complex SQL Server backends - Proven track record of Telerik-to-modern UI migrations - Focus on scalable architecture & long-term maintainability We understand how important stability is for ERP systems, so our goal is zero disruption with a noticeable upgrade in speed and usability. Quick questions: - Do you already have any API layer in place, or will this be a complete transition from server-rendered pages to a fully API-driven architecture? - Which ERP modules are the most business-critical or high-traffic, so we can prioritize them during migration and testing? - Are there any performance bottlenecks in the current system that you'd specifically like us to address during the rebuild? Happy to review your current codebase and suggest a clear migration roadmap with timelines. Regards, Chirag
