We never start a migration engagement without a deep understanding of your codebase. Every project begins with an honest assessment of complexity, risk, and the right strategy for your situation.
A detailed written assessment you own, regardless of whether you engage us further. Solution structure analysis, dependency mapping, third-party component inventory, migration strategy recommendation, and a realistic complexity and risk summary — all in a document you can use immediately.
The assessment is free. You get a document you can use — whether you work with us or not. Share it with other vendors. Use it for internal planning. It's yours.
Timeline: Assessment delivered within 1–2 weeks of receiving access to your codebase. We'll ask for a zip or a private repository link — your code never leaves a secure environment.
Our migration tools are configurable, not fixed templates. Before a single line of your application is transformed, we prepare the tooling specifically for your patterns, your third-party components, and your complexity profile.
We identify every third-party control in your application — Telerik, DevExpress, Infragistics, ComponentOne, Syncfusion — and configure transformation mappings for each. Generic tools skip this step and leave you with broken replacements. We don't.
Every large enterprise codebase has patterns not covered by standard transformation libraries. Our team builds custom rules for the patterns unique to your application. This is the reason our transformation rate is 80–90%, not 60%.
Before transformation begins, we set up the semantic validation framework — the mechanism that ensures the migrated application behaves identically to the original. Tests are generated from your application's logic, not from generic templates.
Timeline: Tool preparation typically takes 2–4 weeks for a standard Web Forms application. Larger or more complex codebases with unusual third-party components may require additional time. We give you a specific estimate in the Phase 1 assessment.
We offer two delivery models based on your team's capacity and preferences. Both include the same tooling, the same validation, and the same delivery standards from our team.
We provide the tools, configuration, and ongoing support. Your team runs the migration using our tooling. We review output, validate transformations, and handle escalations. You maintain full visibility and control throughout.
Best for: Teams with strong .NET developers who want to maintain control and build internal migration capability.
We deliver the complete migrated application using our network of experienced delivery partners. You define requirements and acceptance criteria; we deliver. Our team provides tooling, oversight, and final delivery sign-off.
Best for: Organizations without available .NET developer capacity for the migration, or those who prefer a turnkey delivery.
Both models include: tool support, semantic validation, test generation and execution, and delivery sign-off from our team.
Delivery doesn't happen until the application is validated. Every deliverable is tested against the acceptance criteria defined before work began.
The generated test suite runs against the migrated application. Every test case is derived from the semantic model of the original — covering happy paths, edge cases, and the specific business logic patterns that matter for your application. Failures are documented and queued for resolution.
AI reviews flagged differences between original and migrated behavior. Each difference is classified: transformation bug (fixed), expected platform difference (documented), or agreed behavioral change (already approved). Nothing is left in an ambiguous state.
Remaining issues are resolved through AI-assisted and manual work. Each resolution is validated against the test suite before it is closed. Our team reviews every resolution before it is included in the final deliverable.
Your team validates the migrated application against the acceptance criteria agreed at the start of the project. We provide full documentation of every decision made during migration — so your team understands exactly what changed and why.
Final delivery includes the migrated application, the generated test suite, transformation rule documentation, and a knowledge transfer session covering decisions made during migration. Your team walks away with the full picture — not just the output.
Not developers who discovered legacy migration when LLMs became popular. People who built the tools and ran the engagements that defined the field.
Our team is built from people with 20+ years of hands-on experience in enterprise software modernization. We've worked on the migrations that others said couldn't be automated — the 500,000-line Web Forms monoliths, the deeply embedded third-party control dependencies, the undocumented business logic buried in code-behind files.
We brought AI into this practice not because it was new, but because it genuinely creates leverage at the specific points where deterministic tools have always needed human judgment. The combination works because we understand both sides deeply.
Our founders built Artinsoft — the pioneering legacy migration company — and Mobilize.NET, the industry's premier automated migration platform. Hundreds of enterprise migration projects completed. Millions of lines of code transformed. Clients in financial services, healthcare, insurance, and government.
When we say we've done this before, we mean the engagements that built the methodologies and tools that the entire field uses. Now we're applying that depth of experience to the AI era — where the leverage points have changed, but the discipline hasn't.
This is exactly why the assessment comes first. We size and scope the work honestly — including the hard parts. Our tool customization phase is specifically designed to handle complexity that stops generic tools: unusual third-party components, non-standard patterns, deeply intertwined business logic. We've seen complex before. It just means more preparation work upfront.
Our partner delivery network handles full execution. We've built relationships with experienced .NET development partners who are trained on our tooling and delivery standards. You define the acceptance criteria; they — under our oversight — deliver to them. No internal developer capacity required.
Assessment: 1–2 weeks. Tool preparation: 2–4 weeks. Migration execution depends on codebase size — 50,000 lines typically takes 8–12 weeks; larger projects scale proportionally. We give you a realistic timeline in the Phase 1 assessment, not a number optimized to win the business. Projects we've seen go wrong almost always had unrealistic timelines set at the start.
Free, no-obligation, and useful regardless of what you decide next. We'll tell you exactly what's in your codebase and what a realistic migration looks like before you commit to anything.
