Migrate away from OutSystems.
When OutSystems is no longer the right fit, we move applications to a modern stack in 6 to 12 weeks. You keep your governance, your monitoring and your operational confidence, and you pick up modern AI capability on the way.
The maths has changed for a lot of teams.
OutSystems remains a market-leading platform for the right context, and we still deliver on it every week, including for teams using its Agentic Systems Engineering and Agent Workbench. The conversations we're having about moving usually aren't about whether OutSystems can do AI (it can) — they're about licence costs that no longer match how the business has grown, an acquisition that's shifted architecture decisions, or a strategic call to consolidate onto a different stack.
When that's the right conversation to have, the move itself is far less dramatic than most teams expect. The control low-code gave you (governance, monitoring, code analysis, audit trails) can all be rebuilt on a modern stack. We do it repeatably, with the same delivery discipline we apply to every other engagement.
The worries teams ask us about, and the shape of the bill.
Before the calculator, the things we get asked most often about how a migration actually runs and what changes in your run cost on the other side.
No source code or subscription change
We scope from your application catalogue and a few interviews. Your OutSystems environment keeps running until you tell us the new one is ready, and your subscription only ends when you decide it should.
Large estates move incrementally
Hundreds of applications? We don't move them in one go. We pick the cleanest first, run it in production alongside the rest, then move the next in batches that suit your roadmap.
Data migration is handled, not hand-waved
The trickiest part of any move. We map data in discovery, build the new copy alongside the live one with reconciliation reports as we go, and only switch when the numbers line up. The old environment stays warm during cutover.
Predictable run cost
Run cost on the new stack barely moves with the number of applications or the number of users. Add another tenant or another mobile feature and the bill stays roughly flat.
Every environment, included
Dev, QA, pre-prod, prod, sandbox — whatever shape your team works in. The new stack doesn't charge a tier per environment, so we can match what you already have.
Refresh, not just relocate
Migration is the natural moment to retire the features no one uses, fix the UX that's been bugging everyone, and add the AI capabilities that didn't fit before. We pick those calls together in discovery.
Quick to iterate on the other side
On a modern stack with our delivery setup, teams iterate quickly with the same controls in place. Run cost goes down and ongoing delivery cost moves with it.
Rough numbers, in under a minute.
Pick the bands closest to your estate to see the cost shape, the run cost on the new stack, and the saving against what you're paying today. Discovery confirms the real numbers and locks the price.
How big is your estate?
Pick the bands that fit. We'll show the cost shape, the run cost on the new stack, and the saving against what you're paying today. Discovery confirms the real numbers and locks the price.
Pick a band on the left for a number closer to yours.
Run cost on the new stack barely moves with more apps or users, so the saving compounds as you grow.
Bands are indicative. Discovery runs from your application catalogue and a few interviews, so we don't need source code or touch your subscription to scope it.
Start with a one-week Estate audit.
A lighter, earlier-stage engagement than Discovery. We look at your estate, map the art of the possible on a modern stack, and give you a written recommendation on whether a migration is the right next step at all. No source-code access required, and the audit fee is credited against Discovery if you proceed.
What recent migrations have looked like.
A senior team that knows the platform you're moving off.
We still deliver on OutSystems every week, and we've shipped migrations off it. That gives you advice that's neutral on the platform question, from people who already understand what you're working with.
18+ years on the OutSystems platform
We know what you're moving off, what you'll miss, what you won't, and what to replace it with. Sales & Delivery Partner since 2021.
Two-plus years building with AI in production
One of the things you pick up on the modern stack is native AI capability. We've been shipping production AI for real users for years, not learning on yours.
A repeatable migration playbook
Discovery, parallel build, cutover. Done end-to-end multiple times, with users on a working application throughout.
Every OutSystems pattern has a modern equivalent.
We start by re-implementing what already works, beat for beat. Then we use the new stack to take it further, where it earns the change. Below is the surface area we cover by default, on O11 or ODC.
Your applications land on a standard repository you own, with no platform licence and nothing locked behind a vendor.
Workflows & BPT
Approvals, case handling, long-running business processes. Rebuilt on modern workflow engines that keep the same behaviour and stay visible end to end.
Timers & scheduled jobs
Background work moves to standard infrastructure. Reliable, easy for your team to watch and extend.
Client & server logic
Clean separation between UI and the systems behind it. The two can evolve independently after the move.
C# extensions & Forge
Custom extensions and Forge component logic come across as first-class code. Easier to test, easier to share, no longer tied to platform internals.
Mobile & PWA
Native mobile and mobile-first PWA flows rebuilt with modern frameworks. Push, offline and biometrics handled by mature libraries.
SSO, identity & roles
Existing SSO, role models and audit trails preserved. We integrate with whichever IdP you already run.
JavaScript & front-end
Custom JS, screen logic and bespoke UI patterns re-implemented in modern frameworks, with a design-system baseline so the experience comes through cleaner.
Data & integrations
Existing data stores, REST and SOAP integrations, and ETL flows migrated in parallel and reconciled end-to-end before cutover.
AI that does work end-to-end (new)
A newer pattern that fits the modern stack naturally — AI that completes multi-step tasks on its own, under the same governance you'd apply anywhere else. Included at no extra cost.
Migrations run from OutSystems 11 or ODC. Co-existence is supported during the cutover window, so users stay on a working application throughout.
What you don't lose when you move.
The thing teams worry about losing when they move off OutSystems is usually the stuff the platform handled silently in the background. The four pillars below cover the worries we hear most often — the rest of the practice sits underneath.
Automated testing
Tests at every level, run automatically on every change. Nothing ships without passing them.
Code review & analysis
Code is checked automatically for quality, security and architecture compliance. AI-written code is held to the same bar as human-written code.
Visibility in production
Cost, performance and quality on live dashboards. Every interaction can be replayed for debugging. Nothing hidden.
Security built in
Security woven through delivery, secrets, dependencies, vulnerabilities, not bolted on at the end.
Four phases. Most migrations inside twelve weeks.
Discovery is the only paid commitment up front. It runs against the application catalogue and a few interviews, so there's no need to grant code access or change your OutSystems subscription before you've seen a plan.
Discovery
2 weeks, paidThe scoping engagement once you've decided to move. We work from your application catalogue, a few interviews, and a short data audit. No source-code access required. Output is a migration plan, a fixed price for the move itself, and the lift-vs-refresh call on each application. (If you're not yet sure migrating is the right answer, the one-week Estate audit above is the starting point.)
Migration
4 to 12 weeksIncremental delivery, with users always on a working application. We move things in sensible batches, modernising where it earns the change. Data migration runs in parallel, validated end-to-end before any user is asked to switch.
Cutover
1 weekQuiet switch. SSO, integrations, scheduled jobs all migrated. The old OutSystems environment stays warm during co-existence, so rollback is cheap if it's ever needed.
Support & enhance
Your callShipping isn't the moment we vanish. Most teams keep us in for one of three flavours — a support retainer for when the unexpected happens, continued enhancement while your team builds confidence, or a small care plan that keeps the pipeline, monitoring and AI capability fresh. We're equally happy training your team to take the lot in-house. We say what we'd recommend, then we do whatever fits.
Honest about when to pick this one.
Right for you if…
- Teams whose context has shifted and OutSystems no longer fits.
- Applications where AI ambitions need a different runtime.
- Estates where AO-driven licence economics have changed the maths.
- Teams who want to move without losing governance or observability.
Look elsewhere if…
- Estates where OutSystems is still earning its keep. We'd rather you stay.
- Migrations driven by fashion rather than fit.
- When the right answer is a hybrid estate, not a full move.
