Is this you?
Six signs your app needs modernisation now
Three or more of these describe your system? You're already accumulating technical debt that compounds every quarter.
End-of-life technology stack
Running on PHP 5, .NET Framework, Java 6, or any stack the vendor no longer patches. Every day without an upgrade is an active security liability.
No automated testing
Every release is a manual regression cycle. Developers are afraid to refactor because nothing is tested. Velocity drops with every new hire.
Monolithic architecture
One change in payments breaks the login page. You can't scale individual services. The whole application goes down for every deployment.
On-premise infrastructure
Hardware refresh cycles, unpredictable scaling costs, and data centre risk. Your competitors are 10× more elastic on cloud-native infrastructure.
Talent retention problems
Strong engineers won't join to work on legacy stacks. The team maintaining it is ageing and leaving. Institutional knowledge walks out the door.
Compliance exposure
GDPR, SOC 2, ISO 27001 — your legacy app wasn't built for modern compliance requirements. Every audit cycle turns into a fire drill.
Recognise three or more? — The longer you wait, the higher the migration cost. A free audit gives you a concrete roadmap in 5 business days.
Our approaches
Six proven patterns — matched to your situation
Not every legacy app needs a full rewrite. Select a pattern to understand when it applies and exactly what it involves.
Strangler fig migration
Incrementally replace legacy — no big-bang rewrite
- Large monoliths that can't be taken offline
- High-traffic apps where zero downtime is non-negotiable
- Teams that need to keep shipping features during migration
- 01New services built alongside the existing legacy system
- 02Traffic routed incrementally via API gateway
- 03Legacy components retired one by one as new ones stabilise
Insight — Our most recommended approach for production systems. Continuous delivery throughout — your users never notice the migration happening.
The transformation
What changes after modernisation
Select a dimension to see exactly what your engineers, operations team, and business will experience after modernisation.
One big monolith
- Single codebase — one change risks the whole app
- Scale everything or nothing at all
- Full redeploy required for every change
- One failure takes down the entire system
Independent services
- Clear service boundaries — changes are isolated
- Scale only the services under load
- Deploy individual services independently
- Failures contained — the rest keeps running
How we deliver
A structured process — nothing gets broken, nothing gets missed
Every phase has defined deliverables, a client approval gate, and a rollback plan. You always know exactly where the project stands.
Legacy audit
1–2 weeksDeep technical read of your codebase, infrastructure, database, integrations, and security posture. You get a written report with a prioritised modernisation roadmap before any build work begins.
- Technical debt inventory
- Architecture assessment
- Risk register
- Modernisation roadmap
Architecture design
2–3 weeksTarget architecture defined, migration pattern selected, and a detailed sprint plan locked. You review and approve every design decision before development begins — no surprises.
- Target architecture diagram
- Migration pattern decision
- Data migration plan
- Sprint roadmap
Migration sprints
8–32 weeksTwo-week sprints, each moving a defined slice of functionality to the new architecture. Legacy stays live throughout. Every sprint has a rollback plan and ends with a live demo to your stakeholders.
- Migrated + tested service
- Automated test suite
- Updated architecture
- Sprint demo
Cutover & validation
1–2 weeksZero-downtime production cutover. Load testing, security scanning, and a formal go-live checklist. Both systems run in parallel until the new one is fully validated at real production load.
- Go-live runbook
- Load test report
- Rollback procedure
- Monitoring & alerting
Handover & support
4 weeks+Structured knowledge transfer to your internal team — documentation, runbooks, and paired working sessions. Continue with a managed retainer or take full ownership — your choice.
- Full system documentation
- Operational runbooks
- Team training
- 30-day post-launch SLA

We choose the stack that fits your needs — not the one we're most comfortable with.
Why MayuraSoft
What makes us the right partner for legacy modernisation
We audit before we propose
We never recommend a modernisation pattern without first reading the codebase. Most vendors guess. We read the code — then tell you what's actually needed and why.
Zero-downtime as a default
Every migration plan we write includes a rollback procedure. We've never had an engagement that required using it — but your stakeholders will sleep better knowing it exists.
We don't oversell rewrites
A full rewrite is the most expensive, highest-risk option. We only recommend it when every incremental path has been ruled out. Our incentive is your outcome, not invoice size.
Your team owns it when we leave
Every engagement ends with documentation, runbooks, and training. We're not building a dependency on MayuraSoft — we're building capability inside your organisation.
Dual expertise: legacy + modern
Modernisation requires speaking both languages. Our team has worked on .NET Framework, PHP, Java EE, and Oracle — and with Kubernetes, React, and serverless. We bridge the gap.
Fixed scope, no billing surprises
Modernisation projects are notorious for scope creep. Every change is documented and priced before actioned. The number you approve is the number you pay.
