Legacy modernisation

Future-proof your
legacy systems.

That decade-old PHP 5 application is still running the business — and slowly bleeding it dry. We migrate to modern stacks incrementally, without big-bang rewrites, production outages, or data loss.

The hidden tax

The cost of
doing nothing.

Legacy systems don't fail loudly. They tax you continuously — in security risk, hiring difficulty, slow shipping, and lost competitive ground.

Security vulnerabilities Old framework versions, unpatched libraries, hard-coded credentials. Every CVE published is one more open door.
The hiring crisis Try recruiting a senior PHP 5 developer in 2026. Or jQuery. Or Backbone. Modern engineers won't touch dead stacks — and the few who will charge a premium.
Speed to market Every feature takes 3× longer to ship than it would on a modern stack. Competitors with younger codebases out-iterate you indefinitely.
Our approach

The "strangler fig"
pattern.

Big-bang rewrites fail. Strangler-fig migrations succeed. Named after the rainforest tree that gradually grows around its host until it replaces it entirely — we deploy the new system alongside the old, route traffic incrementally, and retire the legacy stack one module at a time.

  • Zero downtime — the old system runs until each module is replaced
  • Each migration is independently rollback-able
  • Data integrity verified at every step
  • Business keeps shipping features during the migration
  • Risk distributed across months, not concentrated in one weekend
migration.routing
// Month 1
route('/auth/*') → new;
route('/*') → legacy;

// Month 4
route('/auth/*') → new;
route('/billing/*') → new;
route('/dashboard/*') → new;
route('/*') → legacy;

// Month 9: legacy retired.
The roadmap

Migration roadmap.
Five phases.

1

Audit

Map the legacy codebase, identify modules, prioritise by risk and business impact.

2

Foundation

Stand up new platform alongside legacy. Database compatibility, shared auth, routing layer.

3

Strangle

Migrate modules one at a time. Each goes through QA, parallel running, then traffic cutover.

4

Verify

Data integrity audits, performance benchmarks, security scans against the new system.

5

Retire

Final modules migrated, legacy decommissioned, infrastructure costs collapse.

For technical decision-makers

Why your CTO
wants this.

Modernisation isn't a CIO line item — it's an existential one. The CTOs we work with are usually the ones pushing for it because they're the ones answering for outages, breaches, and missed roadmap commitments.

Reduction in monthly infrastructure cost
