OutSystems Migration Specialists
Migrate away from OutSystems. Keep everything that matters.
We move your applications from OutSystems to clean, modern code — React, Next.js, PostgreSQL. Your business logic stays intact. Your licensing costs drop to zero. And you get a codebase any developer can read, test, and extend.
We've studied how OutSystems applications are built at scale. We know what to look for before we start.
You know you need to leave. You're stuck on the how.
OutSystems served its purpose. It got applications built fast, met a deadline, impressed a stakeholder. But somewhere between the second renewal and the third price increase, the math stopped working.
Now you're looking at a platform that costs more every year, runs on a shrinking talent pool, and holds your business logic in a format no one outside OutSystems can read. You know the destination — modern, open, standard technology. The question is how to get there without losing what you've built.
That's where most migration conversations stall. Not because there's no appetite for change, but because the options are terrible:
Detach gives you generated .NET code that won't compile without weeks of effort.
It's technically "your code" the way a car wreck is technically "your car."
Rebuild from scratch means 12-18 months of a team reverse-engineering business logic from interviews and screenshots.
Half of it gets lost.
Move to another low-code platform resets the clock on the same problem.
Different vendor, same dependency.
There's a fourth option. One that doesn't require guessing.
We don't reverse-engineer. We extract.
Other migration firms start with workshops. They interview your users, map processes on whiteboards, and hope they captured everything. We start with your actual applications.
Our proprietary assessment technology reads your OutSystems environment at the architecture level — every entity, every action, every workflow, every integration. We don't need your developers to explain what they built. We already know.
Then we rebuild it in technology you own.
Assessment (1-2 weeks)
We analyze your OutSystems estate and deliver a complete picture: application inventory, complexity mapping, dependency graph, integration catalog, and data model overview. You get a clear scope, realistic timeline, and honest assessment of what migration involves for your specific situation.
No surprises. No vague estimates. A blueprint.
Extraction and mapping (2-4 weeks)
We map every piece of your OutSystems applications to their modern equivalent. Business logic becomes clean TypeScript functions. Entity models become PostgreSQL schemas. Screen flows become React components. BPT workflows become event-driven processes. REST and SOAP integrations carry over with identical API contracts.
Nothing gets lost because nothing is left to guesswork. We work from the actual application structure, not someone's memory of it.
Rebuild (4-12 weeks, depending on scope)
Your applications are rebuilt in React/Next.js with a clean API layer and PostgreSQL database. AI accelerates the implementation. Engineers verify every piece. The result is production-quality code that follows modern best practices — type-safe, tested, documented, version-controlled.
Your OutSystems team participates throughout. Their domain knowledge is invaluable. And they're learning the new stack as it takes shape — this isn't a handoff, it's a transition.
Parallel run and cutover
The new applications run alongside the old ones. Your team validates. Your users test. You switch when you're confident, not when we tell you to. There is zero downtime. Your business doesn't stop while the technology changes underneath it.
Then you cancel the OutSystems contract.
After migration: code you own. Zero licensing fees. Forever.
The codebase:
- React/Next.js frontend — the most widely supported web framework in the world
- Clean API layer (REST or GraphQL, depending on your needs)
- PostgreSQL database — standard, proven, runs anywhere
- Full test suite — unit tests, integration tests, documented
- Git repository with complete history — version control from day one
- CI/CD pipeline — automated testing and deployment
The economics:
- Your annual OutSystems licensing bill drops to zero
- Hosting moves to standard cloud infrastructure at a fraction of the cost
- You hire from the global React/JavaScript talent pool instead of a niche OutSystems market
- No more vendor negotiations, no more surprise renewals, no more pricing leverage held over your head
The independence:
- Your code runs on any cloud provider (AWS, Azure, GCP, or your own infrastructure)
- Any qualified developer can maintain and extend it
- You choose your own deployment schedule, security policies, and architecture decisions
- If you want to switch providers, change hosting, or bring development in-house — you can
Everything in your OutSystems estate. Not just the easy parts.
We don't cherry-pick the simple applications and leave you with the hard ones. Here's what we migrate:
Business logic
Server actions, client actions, data actions, calculated fields, conditional flows. The actual behavior of your applications, not a summary of it.
Data models
Entities, static entities, structures, relationships, indexes. Mapped to clean PostgreSQL schemas with proper normalization.
BPT workflows
Business Process Technology processes including branches, decision nodes, human activities, timers, and error handling. Rebuilt as event-driven workflows.
Integrations
REST APIs, SOAP web services, external database connections. API contracts preserved so upstream and downstream systems don't need to change.
Forge components
Every Forge dependency identified and mapped to a modern equivalent — npm package, custom implementation, or third-party service.
UI/UX
Screens, blocks, web patterns. Rebuilt as React components with your existing design system or a refreshed one.
Security
Roles, permissions, authentication flows. Implemented using standard security practices and libraries.
Scheduled jobs and timers
Rebuilt as cron jobs or event-driven processes with the same schedules and business rules.
You're a good fit if...
- Your OutSystems licensing costs keep climbing and you're wondering if there's a better way
- You're facing the O11-to-ODC rebuild and questioning whether ODC is the right destination
- You've investigated detach and found it's not a viable path
- Your team can't hire OutSystems developers — or the ones you have want to work in modern tech
- You have production applications with real business logic that you need to keep running
- Leadership is asking why software costs keep going up with no end in sight
This probably isn't for you if:
- You're happy with OutSystems and plan to stay
- You want to move to another low-code platform (we migrate to open-source code, not another platform)
Frequently asked questions
For Technical Teams
What if our OutSystems developers don't know React?+
That's expected and planned for. Your OutSystems developers understand the business domain better than anyone. During migration, they work alongside our team and learn the new stack in context. Their domain knowledge doesn't become obsolete — it becomes more valuable in a modern codebase where they can actually see and control everything.
Can you handle applications with complex integrations?+
Yes. We map every REST API, SOAP web service, external database connection, and Forge component. API contracts are preserved so your connected systems don't need to change. We've handled environments with dozens of integration points.
What about our data?+
All data is migrated to a standard PostgreSQL database. We handle the full export, transformation, and validation process. Every record is verified. Your data stays yours — and unlike OutSystems cloud hosting, you have direct access to your database.
Do we need to migrate everything at once?+
No. We recommend starting with one or two applications to prove the process and build confidence. Once the approach is validated, we scale to the rest of the portfolio. You control the pace.
For Decision Makers
How long does a typical migration take?+
It depends on the size and complexity of your OutSystems estate. A single focused application can be migrated in 4-6 weeks. A portfolio of 10-20 applications takes longer, but we work in phases — you see results quickly and can start decommissioning OutSystems applications as each one goes live.
What does it cost?+
Migration pricing depends on the number of applications, their complexity, and the scope of integrations and workflows. We provide a detailed estimate after the free assessment — no vague ranges, no surprises mid-project. For most clients, the migration pays for itself within the first year through eliminated licensing costs.
Is there downtime during migration?+
No. We build the new applications alongside the old ones. Your OutSystems environment continues to operate normally throughout the entire process. You only switch when your team has validated the new applications and you're confident everything works.
What if OutSystems gives us a better renewal deal?+
They might — for this cycle. But the pattern across the market is clear: costs go up, not down. And a discounted renewal doesn't solve the talent shortage, the platform lock-in, or the fact that your code isn't really yours. Migration is a strategic decision, not just a cost negotiation.
