Sitting it out
The software still runs, after all. But every year of waiting makes the rebuild more expensive, the team older and the customers more impatient. Until the first ones cancel.
Legacy to Innovation — we reimagine your software, instead of just porting it
“My software has aged.”
15, 20, 30 years ago you digitized paper forms and changed an entire industry with it. Today most of your development time goes into keeping things alive, while your customers expect web, cloud and AI. There is a path that means neither big bang nor standstill. We call it Legacy to Innovation.
Does this sound familiar?
Your software is a treasure. But it is getting heavier.
Your industry solution has survived the dotcom crisis, the financial crisis and the pandemic, and it still earns money today. Very few software products have managed that. And yet you sense that something has shifted:
- 90 % of development time goes into maintenance instead of new things
- The colleague who really understands the core will retire within a few years
- For VB6, WinForms, Classic ASP or WebForms you can no longer find any applicants
- .NET Framework 4.8 is the end of the line: modern requirements like passkeys stay outside
- Your customers’ next generation will not accept a 20-year-old interface
- SaaS start-ups are deliberately approaching your existing customers
- Releases are unpredictable, every on-prem installation eats into your margin
- And at some point the question comes up: what is my company worth without future-proof software?
Four paths that fail
What does NOT help now.
Lift & shift to the cloud
The desktop application on the iPad via remote desktop: technically feasible, but nobody likes to work that way. The problems just move house.
Automated migration tool
Tools translate the interface 1:1 to the web. The decaying structure behind it stays, and a new dependency on the tool vendor is added on top.
Our customer Odysys tried exactly that and failed with it, before coming to us.Big-bang rewrite
A new team builds everything anew “on the side”. The target keeps moving, the existing developers block it, and it never gets finished.
The better path
Legacy to Innovation: evolution instead of revolution.
The first time, you digitized paper forms, and that was the right thing back then. Today we digitize your processes together: we think through with you how your software really supports your customers’ everyday work, instead of preserving old screens in new technology.
Web-first, module by module
The new Blazor application grows piece by piece and calls your proven legacy application for the modules still missing. Your customers keep working without interruption.
Self-financing
Every stage delivers features you can sell to your customers right away. The modernization pays for itself step by step.
AI-accelerated, with method
Following our own AI-Assisted Software Engineering process, we rebuild your application AI-supported: with architecture, reviews and quality assurance instead of prompting away. Lived daily practice at Odysys.
Business model included
License purchase or subscription? On-prem or SaaS? We are your sparring partner for the business model. No migration tool offers you that.
Your Legacy to Innovation journey, step by step
Every step bookable on its own. Every one is credited.
You never buy a pig in a poke: fixed prices, results guarantee at the start, exit after every stage. All prices net plus VAT.
Orientation
Legacy Future-Check
A structured questionnaire up front, then a 90-minute strategy conversation with André Krämer or a senior architect, together with you as the managing director. A traffic-light assessment along the critical points, an honest recommendation (even when it reads “Wisej is enough for your case”), a 2-page management summary.

Strategy
Legacy to Innovation Workshop
Two days, remote or in Bad Breisig, including preparation and follow-up: architecture analysis, rethinking processes (away from the paper form) and a dedicated module on your business model (license vs. subscription/SaaS). The result: your prioritized modernization roadmap with an effort estimate.

25 % (1,875.00 €) credited toward stage 1
Proof
Modernization PoC — “Stage 0”
Your most important form – reimagined. We build a working proof before you commit. The scope is fixed in writing up front, in screens and process steps. Deliberately without deployment into your environment: the PoC proves the concept, the rollout belongs in the stages.
from 3,499.00 €three tiers, fixed price
Mini PoC3,499.00 €
Your most important screen, rebuilt AI-supported as Blazor. You receive a video demo and source code.
Compact PoC7,999.00 €
A complete process step (2–4 connected screens including navigation), running as a standalone web app.
Full PoC14,999.00 €
Compact PoC plus a jump-off demo into your legacy application, a documented target architecture and a handover session.
Delivery
Delivery in stages
We modernize for you, stage by stage. The technical lead is David Kortmann. Every stage has a defined scope and ends with working software that brings value to your customers. After every stage you decide anew: exit possible at any time, with no loose ends. Know-how transfer to your team is part of it.
- WinForms/WPF → Blazor · WebForms → ASP.NET Core
- VB6 → .NET · Classic ASP → ASP.NET Core
- .NET Framework → .NET 10+ · Azure cloud
- AI-supported rebuild following our AI-Assisted Software Engineering process

Ongoing — you have the choice
And then? You decide how it continues.
After the modernization there are two paths: accompanied or fully taken care of. Both monthly, both without a long commitment.
Architecture sparring999.00 € / 1,999.00 € / 2,999.00 € per month
“Your team modernizes – we accompany you”: regular architecture sparrings, code reviews and access to our reference solutions (Quality Blocks).
.NET maintenance contract498.00 € / 899.00 € / 1,499.00 € per month
“We keep it running”: annual .NET, dependency and security updates, platform monitoring and guaranteed response times.
And if you go the whole way?
Future-Check 749.00 €→Report 3,499.00 € 2,750.00 €→Workshop 7,499.00 € 6,000.00 €→Stage 1 − 1,875.00 €
The Check is fully credited toward the report, the report with 1,499.00 € toward the workshop, the workshop with 25 % toward your first stage.
Which means: anyone who goes further effectively gets the Future-Check for free and carries no risk, because at the start there is the results guarantee.
Proof, not promises
Odysys first tried it with a tool.
ODYSYS – industry solution for heavy-load rental
- Web port with a migration tool on their own: failed.
- With us: architecture sparring, then a web-desktop hybrid PoC, today an AI-supported rebuild of the application in Blazor, stage by stage, following our AI-Assisted Software Engineering process.
- A long-term partnership: from the first architecture sparring through the PoC to ongoing development, on board for years.
- We helped shape the pricing and license model: business-model sparring in practice.
When you do not need us
You just want a quick 1:1 from old to new?
Then you are in the wrong place with us, and we would rather tell you that now than in the proposal. If your processes are meant to stay as they are, and it is only about “the same software, but in the browser”, then a migration tool like Wisej is the faster and cheaper path. Honestly recommended.
We are the right ones if you want more: rethinking processes, reviewing the business model, out of the maintenance trap and on to a growth driver. And if you are unsure which type you are: that is exactly what the Future-Check with results guarantee is for.
Request the Future-Check · 749.00 €Frequently asked questions
Answered clearly.
What does it cost to modernize a WinForms, WPF, VB6 or WebForms application?
A serious answer is only possible after a look at your application. That is why we sell stages instead of flat rates. The entry points are fixed prices and the same for all starting technologies: Future-Check 749.00 €, Modernization Report 3,499.00 €, Strategy Workshop 7,499.00 €, PoC from 3,499.00 € (all net plus VAT, credited toward each other). After the workshop you know your roadmap including an effort estimate per stage.
We still have VB6 or Classic ASP in use. Can you handle that too?
Yes. Grown industry solutions often consist of several generations: VB6 modules, Classic ASP pages, WinForms or WebForms applications on .NET Framework. Our approach is the same for all of them: step by step into modern .NET (Blazor, ASP.NET Core, .NET 10+), module by module. For an insurance company we have been migrating business-critical Classic ASP applications in self-contained packages for years.
Do we have to rewrite our software completely?
No. We work web-first following the strangler fig principle: the new Blazor application grows module by module and calls your legacy application for the parts still missing. Your customers keep working throughout and only notice the improvements from the rebuild.
What we actually want is just a quick 1:1 migration.
Then we honestly recommend a migration tool like Wisej, because that is cheaper for this case. We are the right partner if you want to think through processes and business model as well.
What happens to our own developers?
They remain the core. Either we do the work and your team learns along the way (know-how transfer is part of every stage), or your team modernizes itself and our architects accompany them in sparring from 999.00 €/month. Nobody knows your domain better than your people.
Can you also help with license and pricing models (purchase vs. subscription)?
Yes, it is a fixed part of the workshop (a dedicated business-model module) and of our sparrings. At our customer Odysys we helped shape the pricing and license models; our founder now sits on their supervisory board.
I will take over the company soon. How do I modernize without questioning the founder’s life’s work?
Not against them at all, but with them. Your software is not a legacy burden, it is the proof that the first digitization worked. That is exactly why we work in stages: after every stage the founder sees working results instead of a permanent construction site, their knowledge flows into the workshops, and the new generation adds its own signature without devaluing the old one.
What risk are we taking?
A deliberately small one: the Future-Check comes with a results guarantee (a clear recommendation or free of charge). The PoC proves feasibility before you invest heavily. And you buy the delivery in stages: after every one you have working software and can exit, with no loose ends.
The first step
Ready for 30 minutes that create clarity?
30 minutes, free, no obligation. You talk to someone who understands your software. In the end you will know whether we are the right ones for your project. If not, we will tell you openly.
