Migrate your VFP / VFP9 application to modern .NET and C# with your business logic preserved, your DBF data moved to SQL Server or PostgreSQL, and every output validated against the legacy system before cutover.
Microsoft ended extended support for Visual FoxPro in January 2015 — no patches, no compatibility fixes, no roadmap. For teams already invested in the Microsoft world, .NET (C#) is a natural destination: it shares FoxPro's Microsoft lineage, pairs cleanly with SQL Server, has an enormous developer talent pool, and is a mature, fast, open-source platform that will be well-supported for decades.
Converting to .NET lets you keep the business rules your company has refined over 20 years while shedding everything that makes VFP a liability — the security exposure of an unsupported runtime, Windows-desktop lock-in, the shrinking FoxPro talent pool, and the scalability ceiling of file-based DBF tables. The result is a browser-accessible, cloud-ready application built on a stack you can hire for.
One honest note: .NET is an excellent choice, but it isn't the only one. F8 Labs is stack-neutral — we also migrate to open-source stacks like Go, Node.js, and PostgreSQL. If you want to weigh that trade-off, read .NET vs. open source for FoxPro migration. This page covers the .NET path specifically.
A structured, low-risk migration powered by tooling built specifically for VFP — not a generic rewrite.
Our engineers analyze your VFP / VFP9 codebase, data model, forms, and reports. You receive a detailed scope, timeline, and risk breakdown — at no cost.
Our VFP parser reads PRG, SCX, VCX, and FRX files and documents every rule, calculation, and workflow into a structured, language-neutral specification.
DBF tables and their implicit relationships are migrated to a normalized SQL Server or PostgreSQL schema with full integrity checks and historical data preserved.
Using the logic map as the spec, we build your application on modern .NET — ASP.NET Core APIs and a web front end — with code generators accelerating the CRUD and API layers.
The new .NET system runs alongside the legacy VFP app. Automated tests compare every output record by record until parity is confirmed and you're confident.
We plan and rehearse the go-live, then provide post-migration support, training, and documentation. A partnership, not a handoff.
Every part of the VFP application has a modern .NET equivalent — usually a better one.
VFP forms (SCX) become a modern .NET web UI — ASP.NET Core with React, Blazor, or Vue — accessible from desktop, tablet, and mobile.
FoxPro reports become web-native dashboards, on-demand PDF generation, and Excel exports with role-based access and real-time data.
DBF / DBC storage migrates to SQL Server or PostgreSQL — ACID compliance, foreign keys, stored procedures, and enterprise backup.
VFP password tables are replaced with OAuth2, Active Directory, or SSO, with MFA and audit logging for HIPAA / SOC 2 / PCI-DSS.
Validations, calculations, triggers, and workflows are re-implemented in clean, testable C# — mapped first, then verified against the original.
REST APIs, payment gateways, and cloud services become first-class — the modern integrations that are nearly impossible to bolt onto VFP.
For Pivoten's VFP9 AccountingManager, we exposed live DBF data through a modern API and rebuilt the reporting pipeline — a preview of the data layer that anchors a full .NET migration.
Timeline scales with the size and complexity of the application. The free assessment produces a precise, phase-by-phase schedule — these ranges are typical starting points:
| Application size | Typical timeline |
|---|---|
| Small — under 20 forms | 6–10 weeks. A focused departmental tool with a simple data model and limited reporting. |
| Medium — 20–100 forms | 3–5 months. Complex business rules, multiple roles, and custom reports. |
| Large — 100+ forms | 6–12 months. Enterprise systems with deep integrations and extensive legacy reporting, usually migrated in phases. |
We almost always migrate in phases, starting with a low-risk read-only data layer so you see value early and carry confidence into each subsequent stage.
