Application Modernization Services.

Turn legacy apps into a competitive advantage. We modernise applications to cloud-native re-platform, refactor and re-architect to microservices and containers cutting cost and risk while boosting agility.

Application Modernization Services

Application modernization updates legacy applications — their architecture, code, infrastructure and delivery — to modern, cloud-native standards. It improves performance, scalability, security and agility, often by re-platforming, refactoring or re-architecting apps for the cloud, containers and microservices.

Schnell Technocraft delivers application modernization pragmatically and per-app: we assess each application and choose the most cost-effective path — rehost, replatform, refactor, re-architect, rebuild or replace — then modernise in phases with clear architecture, automated testing and CI/CD. You cut cost and risk, speed up change, improve user experience, and unlock cloud, data and AI — without a risky big-bang rewrite.

Challenges We Solve

The problems we address

Costly legacy

Old apps that are expensive to run and maintain.

Hard to change

Slow, risky releases that hold the business back.

Security & risk

Unsupported, hard-to-secure legacy technology.

Can't scale or integrate

Apps that block cloud, data and AI initiatives.

What We Do

End-to-end capabilities

Engaged as advisory, implementation or a fully managed service.

Modernization assessment

Assess each app and choose the right modernization path.

Re-platform & rehost

Move apps to cloud with optimisation, fast and low-risk.

Refactor & re-architect

Restructure code and architecture for cloud and scale.

Microservices

Decompose monoliths to microservices where it adds value.

Containerisation

Containerise with Docker and Kubernetes for portability.

Cloud-native rebuild

Rebuild apps cloud-native where that's the best option.

Automated testing & CI/CD

Testing and pipelines to modernise safely and continuously.

Integration & data

Modernise integration and unlock data and AI.

Modernization Paths (the 6 Rs)

The right path for each app

A structured approach that maps to how software actually gets built and run.

Rehost

Lift-and-shift to cloud.

Replatform

Optimise on cloud.

Refactor

Restructure the code.

Re-architect

Microservices & scale.

Rebuild

Cloud-native rewrite.

Replace

Move to a better fit.

Legacy → Cloud-native

Modernise without the big bang

Wholesale rewrites are risky and slow to pay back. We modernise per-app and in phases — choosing rehost, replatform, refactor or re-architect by value and risk — with testing and CI/CD, so you cut cost and gain agility incrementally, safely.

Use Cases

Where we help most

Legacy to cloud

Move and optimise legacy apps in the cloud.

Monolith to microservices

Decompose where it adds real value.

Containerisation

Docker/Kubernetes for portability and scale.

Cloud-native rebuild

Rebuild critical apps cloud-native.

Our Approach

How we deliver

A proven method discover, design, build and operate.

1

Assess

Inventory apps and assess the best modernization path each.

2

Prioritise

Rank by business value, risk and cost.

3

Design

Design target architecture and migration approach.

4

Modernise

Deliver in phases with testing and CI/CD.

5

Optimise

Tune, secure and operate the modernised apps.

The outcome

Legacy applications modernised to cloud-native the right path chosen per app, delivered in safe phases with testing and CI/CD so you cut cost and risk, release faster, and unlock cloud, data and AI.

Deliverables

What you get

FAQ

Questions, answered

Application modernization is the process of updating legacy applications — their architecture, code, infrastructure and delivery — to modern, cloud-native standards. It improves performance, scalability, security and agility, often by re-platforming, refactoring or re-architecting apps for the cloud, containers and microservices.
Commonly the 'Rs': rehost (lift-and-shift), replatform (minor optimisation), refactor (restructure code), re-architect (e.g. to microservices), rebuild, or replace. We assess each app and choose the most cost-effective path per application.
Legacy apps are costly to run, hard to change, risky to secure and can't scale. Modernization cuts cost and risk, speeds up change, improves user experience, and unlocks cloud, data and AI capabilities.
No. Modernization is pragmatic and per-app — sometimes a re-platform or targeted refactor delivers most of the value. We prioritise by business value and risk, not a wholesale rewrite.
We modernise in phases with clear architecture, automated testing, CI/CD and coexistence — so we deliver value incrementally without a risky big-bang cutover.
Yes, where it fits. We containerise (Docker/Kubernetes) and decompose to microservices where it delivers real benefit, while keeping monoliths where that's the pragmatic choice.
