// Legacy Modernization
Modernize without stopping the business.
PHP to modern stacks, monolith to services, tech debt to zero — migrated incrementally behind a strangler facade so customers never notice the cutover. No big-bang rewrites, no eighteen-month freezes.
Migration Pipeline Clear
v2.4.0
// 01_migrate_modules
What We Build
Four migration paths, each reducing risk instead of adding a rewrite.
mod_php
active
PHP Modernization
Laravel and CodeIgniter estates moved to typed, testable modern PHP — or ported to Laravel where the old framework was the constraint.

Monolith to Services
Domain boundaries extracted with a strangler facade so you ship every week while the monolith shrinks.

Database Migration
Schema, index, and engine upgrades on live traffic — dual-write, backfill, verify, then cut over and roll back safely.

Tech Debt Reduction
Dependency upgrades, PHP 5 to 8 jumps, framework dead-ends removed, and untested modules put under cover.

Migration Capabilities
The unglamorous work that decides whether a migration succeeds or gets abandoned.
[01]
migrate
Codebase Assessment
Inventory of frameworks, versions, dependencies, custom patches, and the modules nobody dares touch anymore.
[02]
migrate
Dependency & Framework Upgrades
PHP 5 to 8, jQuery removal, framework jumps, and abandoned package replacements with tested rollback points.
[03]
migrate
API-First Decomposition
Screen-scraped and tightly coupled endpoints extracted into versioned APIs with contract tests protecting both sides.
[04]
migrate
Data Migration Engineering
Dual-write, chunked backfill, checksum verification, and a rehearsed cutover with a real rollback plan.
[05]
migrate
Strangler Fig Implementation
A facade in front of the legacy system routing traffic to new services as each domain is proven.
[06]
migrate
Performance Recovery
N+1 queries, cache layers, and index strategy applied so the modern stack actually outperforms what it replaced.
[07]
migrate
Security Remediation
Outdated CVEs, insecure serialization, SQL injection surface, and expired TLS closed as part of the upgrade.
[08]
migrate
Knowledge Transfer
Architecture docs, runbooks, and paired sessions so your team can own the new system without us.
// 03_migrate_pipeline
Migration Pipeline
Five phases, each ending in a shippable improvement rather than a long branch.
phase_01
Assess
Full code and infrastructure scan. Risk register with effort estimates and the two things that could sink the project.
phase_02
Stabilize
Characterization tests around the messiest modules and a backup and rollback drill before anything moves.
phase_03
Strangle
Facade deployed, routing in place, and the first domain extracted and running in production behind a flag.
phase_04
Migrate Data
Schema changes applied online, records backfilled and verified, then cut over with monitoring on standby.
phase_05
Retire
Legacy code deleted, infrastructure decommissioned, and the savings documented for the finance team.
// 04_migrate_output
Modernization Log
Legacy estates moved forward with the business running throughout.
Sample Project
Monolith to Services
Kestrel Decomposition
640k-line monolith split into six services behind a strangler facade, with contract tests at every extraction boundary.
